Can you please explain this situation a bit more in detail ?

Both :-) We want network everywhere, don't we ? :)

what kind of access you'll get then ?

_one_ eth point in each room = private hubs/switches suggested ?

c|should we setup our own wireless infrastructure in the dormitory ?

Ok, we still have time. But we do need some machines for video streaming. As 
many, as we have simultainous talks. I'll ask the CCC for their machines as 
well, but they might want some money for them and we would need to carry them 
from Berlin.

wep provides no security, wpa would be sufficient, but ipsec provides 
additional features (vpns) so I would to provide both (wpa+ipsec) it if 
possible. i did not think hardware being a problem. if it is, we need to 
adjust or plans (or raise more hardware).

could you please describe the network situation there ? is our network 
firewalled from the rest of the university network or only from the 
internet ?

fileserver and ldap+dns+proxy+fai-server are clear to you ? "number crunchers" 
are some fast machines to build on (if we get those).

and i would really display captured cleartext-passwords with a video 
projector. people still need to become aware not to use them or tunnel those 
protocols if needed.
