What is claimed is: 1. A device for impact with a target, the device comprising: a first electrode, a second electrode, and means for deploying the second electrode away from the first electrode, comprising: (1) means for restraining movement of the second electrode with respect to the first electrode; and (2) means for removing restraint of the second electrode with respect to the first electrode after the first electrode makes contact with the target, so that the second electrode initially moves away from the target to make contact with the target a distance away from where the first electrode made contact with the target. 2. A device for impact with a target, the device comprising: a first portion comprising a first electrode for contact with the target; a second portion comprising a second electrode for contact with the target; a tether that couples the first portion and the second portion; and a coupling that facilitates launching the device as a unit, and that, after the first portion makes contact with the target, releases the second portion from the first portion, so that the second portion moves away from the target, to deploy the second electrode on the tether a distance away from the first electrode. 3. The device of claim 2 wherein the coupling comprises a casing and a translating member that moves with respect to the casing in response to impact of the device and the target to release the second portion from the first portion. 4. The device of claim 2 wherein the coupling comprises a fastener that is defeated in response to impact of the device and the target to release the second portion from the first portion. 5. The device of claim 4 wherein the fastener comprises a break-away tab. 6. The device of claim 2 wherein the coupling comprises a latch that is released in response to impact of the device and the target to release the second portion from the first portion. 7. The device of claim 2 wherein the coupling comprises a propellant that propels the second electrode away from the first electrode. 8. The device of claim 7 wherein the propellant propels the second electrode initially in a direction away from the target. 9. The device of claim 2 wherein the tether exhibits elasticity to effect a forceful impact of the second electrode and the target. 10. The device of claim 2 wherein the second electrode comprises a first barb directed in a first direction, a second barb directed in a second direction, and a third barb directed in a third direction. 11. The device of claim 10 wherein the first direction, second direction, and third direction, are mutually orthogonal. 12. The device of claim 2 wherein the second portion has mass that facilitates impact of the second electrode and the target. 13. The device of claim 2 wherein a total mass of the second portion exceeds a total mass of the first portion. 14. The device of claim 2 wherein the coupling uses an energy of impact of the device and the target to release the second portion from the first portion. 15. The device of claim 2 wherein the coupling redirects a momentum of impact of the device and the target into motion of the second portion away from the first portion. 16. A round comprising the device of claim 2. 17. A method performed by a device comprising a first electrode, a second electrode, and an electrode deployment apparatus that deploys the second electrode, the method comprising: restraining movement of the second electrode with respect to the first electrode; and removing restraint of the second electrode with respect to the first electrode after the first electrode makes contact with the target, so that the second electrode initially moves away from the target to make contact with the target a distance away from where the first electrode made contact with the target. 18. The method of claim 17 wherein: the device further comprises a casing and a plug that in a first position restrains the second electrode within the casing from movement with respect to the first electrode; and removing comprises urging the plug away from the first position. 19. The method of claim 18 wherein the electrode deployment apparatus comprises a translating member that translates with respect to the casing to urge the plug away from the first position. 20. The method of claim 17 wherein the removing comprises defeating a fastener. 21. The method of claim 20 wherein defeating the fastener comprises defeating a break-away tab. 22. The method of claim 17 wherein: the device further comprises a casing and a translating member that translates with respect to the casing; and removing comprises translating by the translating member. 23. The method of claim 22 wherein translating releases a latch to remove restraint. 24. The method of claim 17 wherein removing comprises propelling the second electrode away from the first electrode. 25. The method of claim 24 wherein propelling propels the second electrode initially in a direction away from the target. 26. The method of claim 17 wherein the device further comprises a tether that mechanically couples the second electrode and the first electrode, the tether exhibiting elasticity to effect a forceful impact of the second electrode and the target. 27. The method of claim 17 wherein the second electrode comprises a first barb directed in a first direction, a second barb directed in a second direction, and a third barb directed in a third direction. 28. The method of claim 27 wherein the first direction, second direction, and third direction, are mutually orthogonal. 29. The method of claim 17 wherein removing uses an energy of impact of the device and the target. 30. The method of claim 17 wherein removing comprises redirecting a momentum of impact of the device and the target into motion of the second electrode. 31. The method of claim 17 wherein the device is packaged for use as a projectile.
