What I want to do is to stream mpeg4 coded stream instead of mpeg2 to be able 
to handle that on a 802.11b network. I don't want to send a mpeg2 stream on 
the network.

Is that what your first streaming plugin do?
Am i right if i understand "local machine" as the server machine?
How could I write a "client" that pipes the data from the network on the 
"server" machine? what am i missing there...
