we do not need immersadesk.

one is sufficient.

i don't think so.  hank?

We need just a PC running netscape with the real audio, and cosmo player -
good speakers would be good to, and if there is a way to project the
monitor, that would be good too.

not sure if we can supply.  will have to check around  75% sure we can.

not sure, george?  josh?

Tom,
This ap does not require multicast.  All connections will happen through
multiple IP unicast sessions with no multicast router enabling necessary.
