Ok, here's the scoop. It wasn't up last night because it crashed with a bus
error. Anyhow, its up right now and im transmitting.

I'm running nv v3.3beta in cuseeme mode, greyscale, small window, 67kbs.
I'm on and indy sgi which IRIX5, and its also the machine running the
reflector so its a local transmission.

We were connecting with a mac 8100/80av with 0.832b2 and a 486 with 0.70.

We had several other folks (3 or so) attaching with various versions of the
client. We are running it in unicast mode because the version of the reflector
thats up on the white pine server isnt compiled in multicast (at least last
time I checked). I would say at the time it was happening we had 5-6 folks
connected to the reflector with about 3-4 of them transmitting.

In a nutshell, here's what happened.
Two folks were on the reflector transmitting video. Our local mac and a pc in
arizona. I ran sd and spawned off an nv session and connected to the reflector
(same machine). When my signal came up (jher@gehenna.eden.com) it displayed
on the mac as a duplicate of the signal from the fellow in arizona. On the
pc is showed up as a duplicate of the signal from arizona and it was also
alternatively showing what I was transmitting from the camera. It would show
one for about 2 seconds and then update with the other. Flip/flop... I
disconnected nv. Reconnected and it now copied the signal from the mac. flip
/flop. At that point all the clients stopped transmitting so only the sgi
was transmitting and then the signal came through cleanly. Thats how I left
it last night when it crashed with the bus error. It has been restarted now.
