Aside from the fact that it requires a bunch of tech that is not there and
costly to develop (even if you wanted to), it still doesn't solve the
recompile on installation of a package (specially if they contain code,
like designtime editors).

Then there is of course the problem that Java solves by simply not being
multiplatform at all.  (but run inside a Java world with the real machine at
arms length) 

Such universal code system would still fall down at the first OS specific
ifdef.  (since code for only the selected platform would be compiled into
bytecode ).

Yes. And then you would have what exactly? Still only a binary package compiled at
the host binary, the link to the IDE is still not done.

Good to remind, that is also the problem, since like most bytecodes the
intermediate format would be easily decompilable.
