You do realise that you have now told the whole world that you use an
unencrypted X session over a network?  That's at least as bad -- probably
worse -- than using rsh(1) or unencrypted telnet.   I hope you haven't
logged into any sensitive accounts or typed a credit card number into a
web browser over that link...

You'ld be well advised to install putty on your windows box and use the 
ability to tunnel X over a SSH connection.
