hi, last week i was able, with the kind help of several of you, to participate in the Windmer Room conference that is hosting the U. Kentucky's Colloquia each Wednesday, by connecting to the unicast bridge for this event. my question is about these bridges: are they always set and running, or are they ad hoc just for the events? is there one for all the rooms, including the Lobby and Test Rooms? this is a temporary issue for us, as we hope to have multicasting turned back on shortly. but i'm sure emergency situations will come up again, and it's nice to have a backup. also, i wasn't clear on exactly where to find the exact command line info to connect vtc to these bridges. thanks, -gurcharan khanna research computing dartmouth college
