Yes, I would say this is related to OMcast goals. I would prefer that
the interface to the application be an open one - ours is plain
IP multicast, which is about as open as you can get. Although the
ConferenceXP interface is an API that looks to be proprietary from
what I see on the webpage, they must have a group communications
service lower in their architecture and they might be interested
in defining a common standard. In any event I believe it would be
a bad idea to rule out the possibility before learning what interests
they may have.

As I read the abstract, this is an analytical treatment of an important
part of the problem that we have been working on at GMU. Because we are
experimentalists, we have implemented a working prototype and have people
interested in using it; but this thesis appears to be an important
contribution to the theoretical basis of routing in overlay networks. So
yes it definitely fits and thats for pointing it out.
