Cacao VM running on OpenMoko
First, system emulator for OpenMoko based on qemu is really exciting, and I prepared a working Win32 version of openmoko emulator some days ago (look up the wiki for details). Then, back to Free Java world, I met several hackers around the world in #kaffe, #classpath, and #cacao IRC channel. Since I had portd Kaffe to Xscale-based mobile phones, I decide to take Cacao for a try.

However, I still manage to let gtk-peer work on Cacao inside GTA01 device. But I am of the opinion that it is really a good start point for joint of the power from Free Java (GNU Classpath, Cacao, Kaffe, etc.), OpenMoko, and Embedded Linux.
Also, I met guillaum1 in #cacao, who is the developer of MIDPath, and he suggested me to try the combination of cacao-cldc (cacao without GNU Classpath) + MIDPath. The design of MIDPath is very flexible, and it allows to have MIDP2 working on top of cacao-cldc (without Classpath) or standard cacao (i.e with Classpath). I will do that later.
In addition, some friends in Taiwan and I set up a new laboratory, named "Open RazzmatazZ Laboratory" (OrzLab), which funds an environment for freedom and creativity based on Free Software and Open Source efforts. We are looking for some improvements for OpenMoko, such as CJK (Chinese, Japanese, and Korean) text processing and input methods, Java VM integrations, etc. I do really enjoy the fun of hacking!
