increase a counter with your own recvBytes() method in TcpSink,
replacing any dummy method that's already there. I'm lazy and I only
had one sink, so I just stuck a printf in that instead to give bytes
received by the application; captured the output, generated a
cumulative... and posted the diffs to this list.

you might want to create a bound variable instead; this is a common
enough query that a standard way of doing it would be good. All the
TCP niceties are at the sender side...
