The XP servers support encryption (except in French versions of XP) in the
Remote Desktop Protocl (RDP) and so do the clients -- at least, the one
from http://www.rdesktop.org/ , which is what I plan to use.

But how easy is it to crack? I need to be able to access friend's three
Windows desktops once in a while and can setup ssh-tunneling, or simply
configure his firewall device to forward 3 different ports on his public
IP-address to the port 3389 ("rdp") on his three different private IPs.

The second option is certainly simpler -- how dangerous is it? Is the
encryption of the protocol real or is it just some kind of obfuscation
easily openable by anyone, able to sniff a couple of hours worth of
traffic?

Thanks!

Its encrypted at 128-bits so using a *strong password* should be sufficient.

With that said...personally I run RD through a SSH tunnel and use a public/private key with a strong
passphrase verus password authentication.

Just because something has been sprinkled with '128-bit encryption
pixie dust' doesn't mean it's secure. Heck, WEP can use 104 bits and
do you think anyone trusts it? :) 

It all depends on your level of paranoia.
