I am, too. Please reply to the list only.

"high quality, but lossy" makes me cringe, but...

Sure. I suggested laptops for the sake of convenience:
One crew member can carry two cameras, two tripods and a
laptop in one go.

I strongly agree with this. Tapes may be used as a fallback
or backup, but they will most likely never be touched again.

I don't think the space requirement for DV is much of a show-stopper.
Hard drives are cheap, especially for desktop PCs. We don't want to
stream 4 mb/s to everyone, so recompression will be necessary.

Anyone who would like to do a couple of hours of editing work,
every day during Debconf5? (/me raises hand) If there are fewer
editing man-hours than footage hours, the editors have to be
unusually productive!

That can often be the case. If the streams are supposed to be
self-contained, they should include the slides. A full-featured
MPEG4 stream can contain vector graphics, but alas, we can not
expect users to have capable players installed. Most slides will
look OK in 320x240, though.
