Sorry for jumping into this subject so late.
One kind of video streaming already exists in the Coccinella's whiteboard using
QuickTime.
Works on MacOSX and Windows. It is part of the (primitive) whiteboard protocol
which
allows essentially anything to be imported and shared in a whiteboard.
If one user opens a movie that QuickTime is capable to import, it sends a http
link
(as part of a whiteboard item) where the other user can obtain it, which then
just
gets the movie (streaming over http) into its own whiteboard. The user can
start playing
before the download has completed (fast start). It is using http so it can't do
anything about
NATs/firewalls.
It is also possible to just enter a url where a streaming (TV) is found and the
two users
watch the same video (or audio) stream.
This is perhaps not what you wanted, but it shows some of the flexibility with
a generic
and general whiteboard.
I know, the protocol sucks and I really should move towards SVG.
