I played around with the NestedVM... I was able to compile the Lua executable into a MIPS binary and then generate a Java class. Seems to work. Just as an arbitrary test I executed a sieve in both the native and the Java version and the Java version was about 10 times slower (7.5 seconds agains 77 seconds) and consumed a little under 3 times the memory (66MB agains 150MB)... Since the source code it generates is not good (doesn't even compile) I couldn't see if there was a way to export the functions and maybe prepare a pure Java version of Lua from this. There are other possibilities on converting C code to Java, but I think the main problem will be being able to keep Lua fast and using few memory. Espetially using automatic tools...
