*shrug* Whatever :) NetMeeting can read broadcast streams (Just like your
web server serves more than one client at a time (not technically as of
yet, but for practical purposes)?) And yes, point-to-point, both Sync and
Async, involve routers, unless of course you are on your direct LAN, with
the same network block and the same subnet, but how often is that going to
happen in a bigger-than-class-c corporation? I believe I said LAN-to-WAN
and WAN-to-LAN, inclusive in that is that the machines are not on the same
network. A video capture board isn't *always* the solution, especially
when you have cards that are maxed out to begin with, among other
configurations that don't allow it to happen. I was giving some insight on
some possible situations (i.e. the four scenarios I gave), but the
situation at hand is entirely dependent on what the customer's "needs" are
and that isn't always what they "say" they need.
Last....yes, good routers in today's world can handle multimedia in spec
ial, more appropriate, ways.

This is where I stop; this discussion is not for this list.

With NetMeeting (and I would assume most products) a video capture card
will
out perform the Quickcam (or any parallel port camera if there are others)
in both quality of image, as well as frames per second. Winnov makes a
good
card, and most companies use the Phillips camera with their boards. You
can
find the Winnov capture card selling under the Phillips name brand in the
stores. This is the camera configuration preferred by MS, and they test
quite a few with NetMeeting. I have used both types, and the video capture
card types are WAY better.

I am not sure what you are talking about Mitch with the router
configurations, but with NetMeeting, it can only do point to point, and
routing has nothing to do with that. I guess I just don't understand what
you mean. Is there some routers that handle UDP packets better than others
(aside from junk equipment, etc..)?

Also, if you are interested in standards, NetMeeting is standards based. I
am not sure how many others use the same standards, but I have seen some
neat equipment based on it, and I am pretty sure at least Intel uses it.
