SharedAppVNC

NetMeeting has always had a couple features that was missing in the open source world such as application window sharing. But no longer! SharedAppVNC runs on linux and MacOSX (and soon Windows) where it allows you to share an application window, or a full window just like in remote desktop sharing in NetMeeting. It’s basically a hack of the VNC protocol, but definitely still useful when you only want certain people to have access to certain applications instead of sharing the full desktop.
Perhaps this can carry you over until openT120 finishes (seems like the Open T-120 project has currently stalled development).
