I don't claim to be an expert on anything, but I can tell you what EVL has
been poking around with.

The MICE website actually contains some whiteboard software that is part
of their conferencing group of programs. I have tried this software known
as WBD, and it seemed to perform adequately. I believe that it works uner
the same multicast premise as VIC and RAT. As a result, I would imagaine
that it could be integrated into the current AG structure without much
difficulty...but again that's under my own disclaimer of ignorance. You

Well, from a codec standpoint, I believe that VIC and NetMeeting are
compatabile with H.263. However, I think that the AG currently uses VIC
in the H.261 mode. Of course, interpreting the packets of VIC into
NetMeeting and vice versa might be a problem. This issue came up when EVL
was trying to link people to AG an Polycom which failed to work for our
limited, quick test case though I am not sure why.

There is a mailing list on that...ag-hf at mcs.anl.gov or
ag-hf at accessgrid.org...I believe the "mcs" address is probably more
correct. Not a lot of traffic has appeared on this list.
The retreat from last year had a human factors workshop. Proceedings can
