	But that's Sun's proprietary Java, yes?

	Kaffe *is* the Java integrated with my browser of choice.
Kaffe is the *only* free software java runtime.  All the rest have
draconian license restrictions on them.

	There are free compilers, to be sure.  THere's gcj (compiles
to native machine code) and jikes (compiles to java bytecode).  But
that ignores the question of proprietary lock-in on the part of java
runtimes and virtual machines.  There exist great virtual machines,
but the runtime libraries are under lock and key by Sun and Blackdown
and folks.
