I want to add to this thread on tools for asymmetric broadcast of group
events via Teamspeak or whatever. I was one of about 6 folks benefited
by Nancy's enterprise of Teamspeak at Boston.
First I think video is highly overrated for "ambient visuals", like
the proverbial talking head image. If the visuals are actual content
of a demo computer screen that is more worthwhile than talking heads
at a podium or ambient poor quality charts or projected screen content.
Voice alone carries huge content and it is worth the smaller
bandwidth that it needs. If any visual is broadcast, it should focus
only on content that has been prepared as digital images, or if it is a
running computer demo, something like flash format is more efficient
bandwidth ....but I don't know what tool will package flash for
streaming broadcast.
When doing a audio broadcast, Teamspeak can allow the recipients to
convene their own audio chat during intermissions in formal
presentations, but etiquette and some moderator for that process is
important to not interfere with the formal broadcast content.
The internal audio channels can also allow passing questions back to
a moderator at the group location, but it is problematic for a moderator
at that location to use audio mode during presentations.
The keyboard chat channels allow text comment among recipients and
also text channels for passing questions back to a moderator at the
group event.
It is important to keep in mind that the accumulated content of any
text chat does not have persistence and dies whenever the Teamspeak
server goes down intermittently. For this reason, it's important to
maintain formal announcements such as speaker schedules and login
instruction on something like a a group email thread using "reply all".
This succession of emails keeps everyone known to the broadcast aware
of configuration rules and scheduling.
Another better approach for persistence is to prepare a web URL/site
in advance and update it for everything that needs persistence during
the event....don't know if Teamspeak or other tools have a way to mirror
text/chat for persistence.
Ideally any effort to provide asymmetric real time content should
merge into an archive of that same content; Nancy has pursued the intial
pieces. Thanks to Nancy for her April effort which generated zero CO2
from jet fuel per amount of content delivered.

I am VERY interested in Pediatrics.
At the last meeting in Boston, we used TeamSpeak to broadcast the proceedings.
We looked at Gnome Meeting and Netmeeting, which are both supposed to work
together, for Atlanta, but we did not have the bandwidth to use it. The plan
was to use Netmeeting and GnomeMeeting for the video broadcast, whiteboard
and I think instant messaging as well, and Shoutcast for the audiobroadcast.
Frankly, I do not remember all of the logic of that, but I could dig up my
old email on the subject if you are interested.
Typical video broadcasts with a decent resolution chew up the equivalent of a
standard DSL line worth of bandwidth or more. Teamspeak, which is only
Audio, has a lot going for it as you can adapt the codecs to match the
available bandwidth. We did not use the full functionality of Teamspeak by
any means. There is an issue with firewalls for the server though, so I
suspect that you have to do quite a bit of homework before you will be sure
that it or any of this software will function in the setting of your meeting.
We were lucky in Boston in that Intersystems went out of their way to allow
our TeamSpeak server to be outside of the firewall, which was a hassle for
them. We really appreciated the effort put in to keep that network tuned
throughout the meeting.
We could have used Apache to post slides, but yours truly was otherwise
occupied and didn't do it. I hope that if we do this for our next meeting.
If you would like to talk about it, you can contact me off the list as this is
probably already more than anyone wanted to know!

Joseph & Nancy, this may bounce again so please forward to the Hardhats
list if it doesn't show up.
To All,
I believe some of you have worked with Gnome Meeting for the Hard Hats
meeetings. Could someone contact me about success/failures/challenges?
Also, there may be an oppotrtunity to apply for a grant to get monies to
add/improve pediatric functionality to VistA.
Interested parties please contact me. off line..
Thanks in Advance
Alric
