It resembles the AG, where all the nodews "join" a specific multicast group. There are Venue Servers that, as the AG venue server also does, tells the client which multicast group is associated with the selected Venue.

Is it a SIP/H.323 ITU like IP dialing protocol or does it resemble the AccessGrid/VRVS virtual venue HTTPS certificate server model.

ConfXP is more "user-friendly" - you don't need a node operator, unix expert, a magic wand, or need to wave a dead chicken & chant to make it work. 2. The video is much better - ConfXP takes advantage of the Windows Media API's and does a very nice job rendering the video & audio - lipsynch has not been a problem for me in my test sessions with folks in Europe. 3. A "bridge" is provided for multicast-challenged users and to use it, the user simply uses a pull-down menu item on their ConfXP. 4. the integration of the client with the TabletPC is compelling (at least to me). It allows the instructor/presenter to face the "audience" instead of pointing at a screen and allows interactive mark-ups on the presentation. 5. you can specify point-to-point connections for two sites, and it seems to work well for the bandwidth challenged locations. Thats my $.02 Cindy Sievers wrote: Hi everyone, I was just wondering if anyone has had a chance to test Microsoft Conference XP? What are the major differences between AG and Conference XP? (aside from the fact that Conference XP only runs on a windows macine) I was looking at their documentation, and they use the exact terminology that AG does, almost the same equipment list, and seem to have the same results.....but I just wanted to hear from folks who have actually used it.... We are going to do a collaborative education project with a remote site who is leaning toward Conference XP and they want to know what the differences are and what the compelling arguments are for either....
