Deke:

Yes, you have it right.  All of my calls (which were many) on the
"wired" network to various endpoints around the US worked fine and most
of these included both video and audio.  Nearly all calls that involved
wireless endpoints were of unacceptable quality and these were audio
only calls.  There were a few exceptions where audio calls to a wireless
endpoint worked fine but this appeared to depend on time of day,
location, signal strength, phase of the moon, etc. :>)

While use of low bandwidth codecs and codecs that are less susceptible
to packet loss (e.g. iLBC) are helpful, this will not be adequate to
solve the problem of all users sharing a 802.11 connection of the nature
established in the Indianapolis Marriott.

I also think voice is an integral part of "integrated communications".
If 802.x wireless technology is to be used in such real-time application
demonstrations,  QoS metrics need to be established or such
demonstrations will certainly suffer.

I had a voice call with Jeff King late on wednesday morning.  He
was in the demo room, I was in the hallway in a place where my
wireless signal was relatively weak according to my client
indicator.

I could hear Jeff really well.  He reported that I was breaking
up badly.

I checked with him shortly after and he was on a wired connection
while I was (as I said) on a so-so wireless connection.

FWIW, we were both running Session -- me on a Mac Powerbook and
Jeff on a Windows laptop.

Jeff?  Did I get this right?
