Not really. If you can wrap the network socket/pipe you could insert a
byte counter. But nobody does this. Its basically just a missing
feature in the JGit transport APIs. We need a way to also make
transfer throughput available to a ProgressMonitor, and then let the
lower level network code wrap the InputStream or OutputStream with a
counting stream that updates the throughput as data is read or
written.

Its been on my list of "wish I had time for" projects, but never
gotten to for a long time now.
