1. A method of removing a client as a member of a hub network, comprising: receiving, at a server, a removal request of the client as a member of the hub network;receiving a revocation notification that the client is no longer authorized to be a member of the hub network,wherein the revocation notification is received when it is determined that the client has circumvented or broken a rule of the hub network for compliant member devices;disabling licenses for sub-copy versions of bound instances bound to the hub network of the server,wherein the sub-copy versions are stored on the client and are copies of source versions of locked content data stored on the server, andwherein the bound instance is one logical instance represented by the locked content data and corresponding licenses stored on the server of the hub network;sending a disable request to the client indicating the sub-copy versions stored on the client to be disabled such that the client disables the corresponding licenses; andremoving said client as a member in said hub network so that said client is no longer a member of said hub network. 2. The method of claim 1, wherein: said server provides a license for the locked content data bound to said hub network only to members of said hub network. 3. The method of claim 1, further comprising: adding said client to a revocation list stored on said server. 4. The method of claim 3, further comprising: sending said revocation list including said client to a second client in said hub network. 5. The method of claim 3, further comprising: sending said revocation list including said client to a second server in a second hub network. 6. The method of claim 1, further comprising: adding said client to a revocation list corresponding to a root license stored on said server;wherein said root license corresponds to locked content data stored on said server and is bound to said hub network. 7. The method of claim 1, wherein: disabling said licenses includes sending a disable request to said client indicating one or more license to be disabled. 8. The method of claim 1, wherein: disabling said licenses includes updating respective root licenses corresponding to said disabled licenses. 9. The method of claim 8, further comprising: declining to renew said disabled licenses for said client. 10. The method of claim 1, wherein: removing said client as a member includes updating respective root licenses corresponding to said disabled licenses. 11. The method of claim 1, wherein: said server does not remove said client as a member until all of said disabled licenses have expired. 12. The method of claim 1, further comprising: decreasing a device count after removing said client as a member;wherein said device count indicates the number of members in said hub network. 13. A method of disconnecting a client from a hub network, comprising: disconnecting the client from the hub network;setting expiration times on licenses for sub-copy versions of bound instances stored on said client and bound to the hub network, when the client has disconnected from the hub network,wherein setting of the expiration times includes resetting the expiration times if the expiration times were previously set to different values,wherein the sub-copy versions are copies of source versions of locked content data stored on a server, andwherein the bound instance is one logical instance represented by the locked content data and corresponding licenses stored on the server of the hub network; andcomparing said expiration times to a clock of said client. 14. The method of claim 13, wherein: said licenses indicate the expiration periods, andsaid expiration periods indicate periods of time for which said sub-copy licenses are valid. 15. The method of claim 13, wherein: disconnecting said client includes said client leaving a local environment of a server of said hub network, andsaid local environment is a limited area defined relative to said server. 16. The method of claim 13, wherein: said clock is a secure client clock. 17. The method of claim 13, further comprising: disabling said licenses when comparing said expiration times to said clock indicates that said expiration times have been reached;wherein said client does not decrypt said locked content data when said licenses are disabled. 18. The method of claim 13, further comprising: attempting to request new licenses from a server in said hub network. 19. The method of claim 13, further comprising: attempting to reconnect said client to said hub network.
