thanks for the partizipation on this topic , i was "theoreticly "
speaking and this was actually what i wanted to hear ;)

i was reading some papers about multicast activity on 9/11 and it was
interesting to read that it just worked even when most
of the "big player " sites went offline, so this gives me another

so this is similar to a "wallet garden " and not what we really want ,
but i was clear about that this is actually the only idea to implement
a "new" technologie into an existing infrastructure.
