I've designed several VMs with these kinds of constraints. One 
of these was modified to become Europay's Open Terminal 
Architecture. The specs may well still be in the SmartCard 
section at www.europay.com.

One has to ask the question of why roll your own when there are 
many such systems already in existence? It certainly is great 
fun, but since there are people like us with VMs and compilers 
already in place ...
