[opensuse] Connecting to a windows machine running PC-DUO

Is there a way to connet to a desktop running PC-DUO? I have to acces several machines running XP and PC-DUO at work. I can (of course) use the PC-DUO software under a MS XP machine, but as i haul a Linux'ed laptop i want to have the same possibility. As it is now i am not able to install any from of VNC on the windows machines. (Due to certification of platform, software and shit (blame it on the IT dept, not me)) -- /Rikard Johnels
