I would love to see an NX client to handle forwarding X sessions with some compression. It would be really nice to securely access my machine at home with such a thing. Right now I can do it over ssh "ssh -X user@hostname" and then run an app or two. I even did the xvkbd thing to be able to type in the forwarded window, but it is a little hacky, and not quit as satisfying as if there were a native application "hildonized" for such a purpose.
