VNC is really a screen/computer-sharing/duplicating protocol, not an
application-sharing mechanism.

ITU specs that Remote Desktop Protocol (Windows) and rdesktop are built on:

T.128 Multipoint application sharing (link seems broken at the ITU)
http://www.itu.int/rec/T-REC-T.128-199802-I/en (T.128)

T.125 : Multipoint communication service protocol specification
http://www.itu.int/rec/T-REC-T.125-199802-I/en

http://en.wikipedia.org/wiki/Remote_Desktop_Protocol
"Based on the ITU T.share protocol (also known as T.128), the first version
of RDP (called version 4.0) ...".  Version 6.0, launched with Vista,
"incorporated support for connecting remotely to individual programs"

Well, this IS the Audio/Video Transport group, not the RTP group.  On the
other hand, most of application sharing isn't audio or video.  And to show
my geekiness, on the gripping hand, the question is whether there's a
better place for it than AVT - should we adopt it because it fits us better
than anyone else?  (I don't know that it does, but that is the question.)
