(challenging assumptions)
why is it realistic to assume that you're on a DSL line?
In Kansas City, a hundred video streams each doing 100 Kbits/s or so may 
be a completely realistic way of doing conference-participation 
thumbnails; it's only 10 Mbits, which isn't that much on a gigabit link.

(with today's codecs, CPU may be a more limiting factor. It's the DSL 
part I reacted to.)
