Two other projects that might be useful to you guys:

  GNU Lightning, a multiplatform JIT framework. IIRC, it is also
  used in GNU Smalltalk. <http://www.gnu.org/software/lightning/>

  vmgen, a system for generating virtual machines from a machine
  description. It builds fast VMs that use a lot of the canonical
  optimizations, like threaded code, putting the top of the stack
  in a register, etc. <http://www.complang.tuwien.ac.at/anton/vmgen/>
