Since I have a N810 now I don't really have the motivation to work on the transparent keyboard xterm.
Before I got it though I was working on a really transparent version (using cairo), which allowed for external creation of the way the keyboard was looking.
Unfortunately the N770 was too slow for real transparency.
Now that you threatened with the FSF I got the impulse I needed to at least see how fast it is on the N810.

So I installed the Chinook and tried to build the xterm. Unfortunately it's not just a matter of rebuilding with the new SDK. Since apparently the API changed, some porting will be necessary. Hopefully in a day or two I'll be done with it.
