Thanks for the detailed information..I learn something new every day :)

I take this to mean H.323 standardized chat doesn't exist? So even
outside of CU, if a Intel Videophone user connects with a Netmeeting user,
they can't share chat? But they can share the Whiteboard?

I know H.323 is fairly I'm not surprised the nitty gritty details
haven't been laid out yet (I'd still love know the status of H.323
multipoint calls..last I read in comp.dcom.videoconf, H.323 multipoint was
limited to multicasting only).

Perhaps I just need to play around with the software more. Allowing
multipoint calls in an environment that only supports point to point
connections is a pain to deal with. While White Pine may have done what
was needed to accomplish it, it's still a messy way to handle it. Ideally
Netmeeting and the other H.323 programs would support multipoint point
calls so you can actually conference with multiple people on the screen at
once. I guess you make the best of what you can at the time.

I'm hoping eventually it will be though :) Right now H.323 is perfect for
White Pine's new market...the corporate users who might actually be able
to benefit from H.323 (and whiteboarding and multicasting..etc)

I'm hoping that changes some day...the videoconferencing market (both the
corporate AND the home users) is constantly changing though... With IPv6,
things will change drastically I believe... I think what's being done
today far exceeds the expectations of the internet as a whole (It wasn't
really designed for real time video and audio traffic.)
