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.

AG Tech, Bob, and Cindy,

How does Conference XP initiate, maintain, and teardown the connection
between sites/nodes?  Is it a SIP/H.323 ITU like IP dialing protocol or 
does
it resemble the AccessGrid/VRVS virtual venue HTTPS certificate server
model.

Thank you,

John

Here are my observations (overlooking the Windows-only thing):

1. 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

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....

Thanks
Cindy
