I was just looking at a similar package for Windows called utorrent. They
relay the remote administration through a third party, presumably to help
non-technical users understand NAT traversal.

Similar problems exist, but you can use it to set configuration options that
result in command execution. I guess this problem is public as their contact
address is a public bug tracking system (mea culpa).

I have a working demo for command execution, email me off-list if you want
it (I'm reluctant to send too much information about windows software to the
list, as journalists tend to abuse it, email me if you need specifics).
