Is there any project out there that does, on the ARM platform, something similar to what WINE does on the x86 platform?
It should be possible (I think!) to do system-call and hardware emulation without having to do CPU emulation, so you could run PalmOS 5+ (ARM-based) or PocketPC (also ARM-based) apps on the Zaurus, much in the same way that, on x86 you can run many WinBugs apps under WINE without doing CPU emulation. This should be MUCH faster and probably more memory-efficient than QPOSE (in the case of PalmOS apps).
