Try playing with the window on a UDP session, on a header with IP-AH or
IP-ESP present etc. There are fudged ways of emulating receive flow control
for tcp - both fiddling with the packets to fake window sizes (dangerous)
or dropping some acks (running a model on the receive side to see which frames
didnt logically make it through) but nothing will keep the flow right on
the receive side the moment someone uses something like NFS or realaudio
over it
