Have I missed something here? Why can't you download all the classes
from an http server at runtime? Like a Java applet does; you just
install a new URLClassloader as the first thing you do with the
appropriate URL. Sure, you'd need them 'round at compile-time, so I
guess a source distro wouldn't work, but a binary distro should be
ok... shouldn't it?
