IGMP goes up to the multicast router or duplicating device e.g. the next switch
- not the multicast source. For the network mentioned we are talking about 10
Cisco 7604 and a couple Cisco 6509 switches which provide the ports. The
multicast source is far away.

I am not shure i like it but probably i'll accept patches ...

Nothing CPU intensive has to take place in getstream to make it clear. 
Getstream should be a low latency, low overhead demux.
