I haven't seen these yet just heard about them. My guess is there will be
as big of a market for them eventually that there have been for the low
cost Quickcam (even though I've heard their frame rates might be even
worse than the Quickcam and demand more from the processor).

Sure..just email me when you get back.

To be clear, I was on Netmeeting, she was on Netmeeting and I could see
her fine. I was on CU 3.1, she was on Netmeeting and I could see her but
she couldn't see me (even though I was using the H.263 codec). I haven't
had a chance to try out the audio with it yet.

Ahh..another standard for whiteboarding. From the email I got about 3.0
from a WhitePine employee, he mentioned that the WhiteBoard is really only
available to those with higher bandwidth. I've never had any success at
whiteboarding on a 28.8kbps modem. Perhaps I expect too much though. At
this point, I've never had the need to use the whiteboard. (I also don't
recall seeing a Whiteboard available for downloading for use with the
preview version of 3.1)

I want to talk to you more about this. I know MeetingPoint has a few
controls for this. I've only seen the one person I was testing it with so
I haven't figured out how things are supposed to work. There's the main
MPCS window and people are switched in and out of it? Does that mean that
one window switches every few secs/minutes to show the video of others?

I was hinting at perhaps limiting a conference to only allow H.323 clients
(with the right audio/video codecs). I'm not sure how lurkers are handled
though. I had an experience when I was playing with NetMeeting on the
White Pine MeetingPoint Commons reflector where someone I hadn't seen at
all started talking with audio to me. I wondered who that might be since
I couldn't see them.

Hehe..It's good to know the only target is no longer the commercial market
with lots of internal LANs.
