[AG-TECH] Conference XP vs AG

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
