To me, more interesting than distributing a fat (or pre-compiled for

exploits all the features of the target.  For instance on x86 systems
being able to use SSE registers as part of the ABI improves its fp
performance.  This ability is one of the ideas behind compiler
projects such as

I think you raised this opinion a few years ago. I like the idea too, since it also follows the concept of "compile once, run anywhere"; something I think that fat binaries can (almost) provide with minimal effort.

Do you have any more ideas about this? A quick look on wikipedia didn't reveal anything that would permit a "proof of concept" to be implemented quickly. Given that NetBSD in written in C, bytecode which could represent the C language seems like an obvious starting place.
