Yes, I plan on releasing the source code, as I indicated in my original e-mail to the maemo-developers list. I'd like to clean it up a bit first.

Regarding the port to rdesktop, I examined the source code for rdesktop last weekend, and it looks like the port should be relatively straightforward. In rdesktop, the user interface is implemented separately from the underlying protocol, so it's just a matter of adding a new user interface implementation. I was thinking about working on this port myself. If I were to port rdesktop, I would start with the Qt UI implementation and convert it to GTK/maemo.
