Interesting... so why does --bwlimit solve the problem? surely the packets
are still the same? Am I showing my ignorance of networks?

I've had the exact same problem you're having (down to scp OK, rsync not)
and clamping my MTU to 950 solved it.  In this case, I had a Cisco box in
between which *may* have been the cause, but I suspect the problem is more
likely to be a bodgy NIC in the mix somewhere.

For some reason, SSH/SCP doesn't seem to produce packets that are quite so
big, but rsync seems to just lurve producing network-choking packets.
