Is this range registered already (details in the link above)?

According to the documentation in the 27C3 wiki it will be RTMP:
http://events.ccc.de/congress/2010/wiki/Documentation#Streaming

As multiple streams are available AND it's kinda regular that streams
break down priorizing all RTMP traffic might be an option, with highest
priority on the official streams which should originate in the 27C3
subnet.

If it doesn't people will complain anyway. ;-)

Okay, regarding other preparations:
As of 24th of Dec Patrick and I checked all (4) of the projectors if
they worked:
- 1 projector works fine without any notes
- 1 projector works fine but carries a note about its fan being broken.
We couldn't confirm this in our quick test as the fan worked properly,
but we did no long-term test regarding overheating
- 1 projector works fine but has 1/2 area(s) with vertical black lines.
If necessary this projector can be used to watch the streams, although
the vertical lines might irritate at first.
- 1 projector needs a new bulb, but seems to work fine otherwise.

The BIG SCREEN works fine too if some (unnamed) people could stop trying
to run remote shutdowns on that maschine (or otherwise I'll change the
login password or disable the shutdown command).

Regards,
BenBE.
