You might also consider using partial evaluation techniques.
Programs that contains interpretation layers are the ideal
targets for program specializers. Please visit our web pages
for more information: http://www.irisa.fr/compose

Tempo, our partial evaluator for C programs, has obtained
speedups from 10 to 100 on various interpreters. I should
be publicly available at the beginning of April.
