Emacs tramp to edit remote files on Windows from Linux

What is the best way to edit remote files on a Windows box (XP) from Linux?

I am running emacs 23.3 locally under Linux.

I would like to keep the extra software on the windows-box minimal, but I can install some extra software if needed. Cygwin is already t开发者_C百科here.

If cygwin is already there, running a sshd in the windows machine and using Tramp (maybe using the scp method) is the best option to my knowledge.
