It is very similar to what Chrome and Firefox are doing for Java
Script. Both now use JIT compilers to covert interpreted code into compiled code, making their JS implementations a lot faster.
I would have thought any program that makes use of the Dalvik Java engine as opposed to Native Code will see a speed benefit here.
I think we're due to find out for sure next week and Google I/O.
