In any case, I would not suggest we rely on being able to use more than
a fraction of that bandwidth for video streams.

Daf, the way we've done streaming at DebConf so far (7 years now?) is
shown in:
Each stream is sent to a single internal server (localstream1).  There
is a single external relay (krusty) pulling from localstream1, and then
multiple additional relays pulling from krusty.  Thus, streams are
available to internal and external viewers without multiple copies being
sent over the WAN link.

I'm still unclear on whether you can use Icecast for the subtitled WebM
streams.  If so, then a similar arrangement should be possible.  Ideally
we could use the same set of relay servers.

I say we take off; nuke the site from orbit.  It's the only way to be sure.
