11. The system of claim 8 , wherein the application portal instance is selected from a set of pre-configured single-use application portal instances, and wherein the single-use application portal instance is selected prior to deployment.

12. The system of claim 8 , wherein the collaboration service is configured to provide any one or more of the features from the group comprising: video conferencing; voice group conferencing; person-to-person telephony; group text chat rooms; person-to-person text chat; file sharing in either direction; sender-controlled email that can be read and replied to; and virtual desktop infrastructure.

13. The system of claim 8 , wherein the second client device is configured to communicate over the private network without a native version of the collaboration service installed.

14. The system of claim 8 , wherein the single-use application portal instance is provisioned with a one-time-use credential associated with the non-registered user.

15. The system of claim 8 , wherein the single-use application portal instance is a platform as a service (PaaS) providing an indirect, single-use connection to the collaboration service.

16. The system of claim 8 , wherein the single-use application portal instance is a software as a service (SaaS) providing an indirect, single-use connection to the collaboration service.

17. A system for facilitating communication between users of a collaboration service on a private network, comprising:
