1. A node comprising: a circuit; said circuit being configurable based, at least in part, on control signals external to said node to be applied to said node via a power distribution system formed when said node is coupled to a plurality of nodes; said circuit including the capability to deliver and to interrupt the delivery of power to said node via said power distribution system. 2. The node of claim 1, wherein said power distribution system includes a serial data bus specification compliant power bus. 3. The node of claim 1, wherein said node comprises a desktop personal computer (PC). 4. The node of claim 1, wherein said circuit includes the capability to operate as a power conduit between the nodes of said plurality. 5. The node of claim 4, wherein said circuit includes the capability to sink power from the power distribution system and source power to the power distribution system. 6. The node of claim 1, wherein each node of said plurality of nodes includes a circuit substantially similar to said circuit, said circuits including the capability to form independent power domains based on externally derived control signals to be applied to each of said nodes via the power distribution system. 7. The node of claim 1, wherein said circuit includes the capability to detect when the voltage of power being sinked to said node exceeds a predetermined voltage threshold of said node. 8. The node of claim 1, wherein said externally derived control signals comprise digital signals. 9. The node of claim 1, wherein said circuit further includes the capability to deliver and to interrupt the delivery of power each port of said node via said power distribution system. 10. A method of distributing power to a plurality of nodes coupled via a power distribution system comprising: applying externally derived control signals to each node of the plurality of nodes; delivering power to selected nodes of the plurality of nodes based, at least in part, on the applied control signals. 11. The method of claim 10, and further comprising: interrupting the delivery of power to other selected nodes of the plurality of nodes based, at least in part, on the applied control signals. 12. The method of claim 11, wherein the delivery of power is interrupted to selected ports of other selected nodes based, at least in part, on the applied control signals. 13. The method of claim 12, wherein power is delivered to selected ports of selected nodes, based, at least in part, on the applied control signals. 14. The method of claim 13, wherein independent power domains are formed based, at least in part, on the applied control signals. 15. The method of claim 10, wherein power is delivered to selected ports of selected nodes based, at lease in part, on the applied control signals. 16. The method of claim 10, wherein the power distribution system comprises a serial data bus specification compliant power bus. 17. The method of claim 10, wherein said externally derived control signals comprise binary digital signals. 18. A circuit comprising: a digital electronic circuit; said digital electronic circuit being configurable based, at least in part, on control signals external to said circuit to be applied to said circuit via a power distribution system formed when said circuit is used to couple a node to a plurality of nodes; said circuit including the capability to deliver and to interrupt the delivery of power to said node via said power distribution system. 19. The circuit of claim 18, wherein said power distribution system includes a serial data bus specification compliant power bus. 20. The circuit of claim 18, wherein said node comprises a desktop personal computer (PC).
