Subset are probably possible. Full implementations, probably
problematic.

Problema in

    1) Lang integrability, where Lua builder award is "C" only.

    2) Biblio programm code, he volume.

    3) Test & bags finding. ( on universal VM link bags be many )

    4) Realization new idea. ( on universal VM realization be slow, so idea be more )

    5) Market niche of Lua, where Lua builder award is embeded system only.

I think CLR and Parrot already solves the multiple scripting
language problem in a more practical way.

You think? This Idiotism? The history CLR is aggravated theft, w/o transplantability. And now writing DotGnu&Mono. So it`s blunt way, using bad technology in your work.

After fixing up the Lua VM to implement various languages efficiently, you'd probably end
up with something like CLR or Parrot. So, why reinvent the wheel?

If we must serve MS & Perl, then Yes it is. You see Parrot VM? It is .... very, vary ... bad & JIT :)

Something with Lua VM is probably better for language subsets, so
for general interpretation of language sources, it won't fit the bill.

Yes, using one VM for all langs impossible, only simple VM langs may be compile to Lua, and this work may do Compiler.

If designer the Lua VM, so only for optimizing Lua: optimum, faster, usable & transplantability.

 

So if something necessary, than Lua write on C++, w/o GC, with simple boost interface to C++ game code.

 

I don`t think.
