I would like to run a little memory mapping note utility like Kdissert on my N800. could I do that without prohibitive difficulties because it is a KDE program? Another cool and similar program is VYM. There's also one called freemind, I think, but it wants Java.

I am typing this from inside of Windowmaker, which I also think it would be fun to be looking at on my N800. How much of a hassle would it be to do that?

A prototype of WM already runs on the tablets. Just look around in recent theads.
