I think the frontend (parsing the language into a tree structure) can
certainly be shared, i'm not sure about the further back stages.
Bytecode environments are certainly very different from native code in

I think to produce a viable compiler you have to. Bytecode environments
don't let you access memory directly so you don't have much choice but
to use the class/interface structure provided by the bytecode
environment. Furthermore all the standard libraries for the language
rely on them as an interface so not being interoperable with them would
be a huge pain.
Lukilly other than the garbage collection issue delphi style object
pascal and java/.net actually have pretty similar object models so it
shouldn't be too hard to map them.
