Have you used it?
How many people can connect simultaneously?
One of the advantages of the streaming format is that the number of
viewers is only limited to the server 'power' to feed them on the
technical side. Because they can't 'talk back', the direction of
participants isn't needed.
On the sharing of communication/messages side, though, when
synchronous communication systems are used where the remotes can
'talk back', the participation must be managed more closely with
better protocols. One of the nice aspects of a twitter or IRC channel
is that it self-manages and doesn't cut across the main content. If
they linked directly in with sound in particular, the noise
interruption problems multiply if there isn't a way for a moderator
to shut it down during presentations. Even with small numbers in VCs,
the amount of mic noise from paper rustling, bad mic placement, side
conversations, etc. is a problem. Now multiply that to LOTS of places
with people who don't know how to properly use a microphone and
you'll get the idea of the associated challenges. Pia would have a
different set of problems to prepare for and the clarity and quality
of the program for participants would go down.
Having a mutable audio channel or even an integrated data channel,
say, feeding twitter questions back through the video feed during the
Q&A, would be interesting to try. Check out what the ABC show Q&A
does for a possible model, Pia.
We did multi-site broadcasts to large audiences using videoconf when
I was in Arizona, way before streaming on the net that opens up to
almost anywhere participation. We had moderators in each
participating site to coordinate input. That was because these were
not existing groups like classes of students. The norms of
class"room" behaviour has a lot going for it when a group is normally
together. And tutors and teachers have a bit of power and authority.
But in an open forum situation like the networked environments, and
especially when the remotes are not seen, the norms aren't there in
the same way.
Hope that helps the thinking.

Our truest response to the irrationality of the world is to paint or
