I'm not sure about that. Some people have produced algorithms that can
adapt the video bandwidth regarding the reported packets loss. However,
that is not implemented in GnomeMeeting and I don't think I'll have the
time to do it soon due to the SIP support which also requires much
time :(

Can you elaborate on this please?
