A serious JIT compiler is going to require some low level work as well. I think the strategy would be to provide an optimized C reference version and then let people provide further optimizations to that as they see fit. > Back to the language wars again :) This does not necessarily follow. > Try googling for the 'squawk' VM - they had a poster at OOPSLA last > week.

The first thing you'd probably want to do in any case is an emulator... although this already exists and is quite nice: http://www.barteo.net/microemulator/ >From my quick glance at the code, I don't think it's checking to make sure that you stick to the MIDP profile - it's basically just an implementation of the lcdui GUI code. -- David N.
