[LAD] Non Session Manager Distributed Session Demo

Here's another video, this one demonstrating the fact that NSM can manage a single session with clients spread across multiple machines (nsmd must be running on each system). http://youtu.be/xzspJXbEoc0 I forgot to show that when you add a client via the GUI, it asks you which server to start it on. Otherwise, the behavior is identical to having a session on a single machine. If you just start up an NSM capable client on any of the machines participating in the session (with the appropriate environment variable set), then that client will join the session as normal. This distributed session feature is just a natural consequence of the architecture of NSM and doesn't add any complexity to either the client or server implementation (just a small amount to the session manager GUI). I'm getting pretty close to doing the release, but I still have a lot of documentation to write and update for the user interface changes. Enjoy!
