Typical Smalltalk VMs do dynamic translation (a.k.a. Just-In-Time
compilation, or JIT for short) from bytecode to machine code,
as do Self and a number if JAVA VMs. In the Smalltalk arena
Squeak has a Jitter and is available for free. Self supports
SPARC and PowerPC and is available for free. The Sun HotSpot Java
VM is available under a quasi-open-source license and supports
x86 and SPARC. There are others which are free.

Threaded code is an interesting intermediate.
