After following [KDE Contributor and Developer Conference], I found the topic [There is a K in microkernel - Qt/embedded port to L4], and I thought that's amazing to me although I can't attend the session due to physical distance. Recently, [the L4 guys] ported Qt to L4/DROPS, and they are finally about to present their great work in KDE aKademy.
As I recall, Alexander Boettcher told me the progress of Qt and Kaffe porting to L4 in mailing-list. Refer to [problem using QtAWT with 1.1.5 (Gnu Linux/i686)]. I am really excited that it works even better now. Later, I would like to put the sexy screenshots in Kaffe.org's collection [Screen Shots - Kaffe's Qt AWT backend], and, of course, I am willing to see the L4 porting efforts are going to be merged in cvs repository, too.
Exciting L4 !
