But they are using qemu. If qemu was closed source, then iEmulator wouldn't have
been able to do that.

Of course qemu isnt under the GPL at all, so that is impossible. Only qemu-user
code uses the GPL license, and that is probably due to the fact that it uses
linux kernel code.

qemu system emulation is under the BSD license iirc.

I agree, but the main problem would be legal. If you can't get the courts
to side with you, then you're sunk.

Presumably he's going to sell kqemu, and he is using this as a test run before
he tries to sell the code to the big companies and get the megabucks. (At least
that is what I would do.)
