I was using Windows Messenger 4.7 before. I'm behind an ISA Server, with the
setting (msmsgs) on the ISA server which allows messenger file transfers
from internal machines.
I would usually get around 80Kb/sec sending file to others, didn't matter if
the other people were behind routers or not.
With MSN Messenger 6, I only can get like 1-2KB/sec. I even tried to
duplicate the ISA server setting that i had for Windows Messegner for MSN
