hello all ,

  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.
