Carl Kesselman at USC/ISI has generously offered to let GRAAP-WG use their H.323 "MCU" which is basically a central controller to allow multi-way video and audio conferencing, including telephone bridging (by dialing a number in Los Angeles). He thinks it can host at least 16 participants, though I am not sure at what point it becomes silly to try to use video. :-) We would need to get a few willing experimentalists to try to test out the waters before actually scheduling a GRAAP-WG working session on it. I am trying to guage interest and I will then coordinate w/ people in his group to find out how we can test and use it without undue load on his staff. Are there GRAAP-WG participants willing to experiment with a software or hardware H.323 client on their end at possibly strange morning or evening hours? I will test gnomemeeting software on Linux from here, and standalone or PC-based Polycom video conferencing should also work fine. I will only be trying the audio capability at first, but those with video capability should be able to see one another too. I think there is a registration/manager process to associate H.323 client IP addresses w/ sessions or "rooms", so it requires a little more coordination than dialing a single remote peer. karl -- Karl Czajkowski karlcz@univa.com
