There has been quite a bit of work on clustering based on virtual
machines (I vaguely remember some work done on a distributed Lisp system
at Tokyo Institute of Technology, that was in '98 though!). All I've
heard have been research-level stuff.

If you want to distribute compiling then it should be possible to use
cross compilers and rather complex setup of distcc. (There's another
distributed compiler used in KDE as well, icecream I think it's called.
It might be worth a check.)

Software is not manufactured, it is something you write and publish.
Keep Europe free from software patents, we do not want censorship
by patent law on written works.

worse.
