One of those click through licenses for the sources from Sun.

It means I cannot charge for the binaries either, which is OK with me.

(Anathema (sp) though it may be, nobody is obliged to share their sources for the
binaries they freely distribute, which I find curious.)

I can share it with anyone that says they already have agreed to the sources, so I
suppose anyone that says they have agreed to the licence can email me, and I will
send my diffs or a tar ball or something.

A number of people have asked for it, including one of the people at Sun who worked
on it (flattering I suppose), so I will have it publicly posted on a page somewhere
that has a button on it to aggree to the sun license... blah blah blah...you know
what I mean.  Point is that I am willing to freely share my work on this, including
the source I have modified.

For more info, I would take a look at www.kvmworld.com, where I found the patches
to make it work on Linux.

It seems to be working great on X11 and X11 hosted NanoX.  Porting the X11 bits to
NanoX was straight forward, since the source and docs are well done.

I quite agree.

I think Nanox is is just thin enough to be well performing, and thick enough to be
a really handy portable API.

KVM is supposed to be a limited JVM - no RMI, nor floats, nor beans.  :(  [But
since the source is there, we can add it.]

But for simple stuff, GUIs and comms, it looks like it is just the ticket for
hardware constrained devices like PDAs and mobile phones.

I have a whole bunch of ideas I think are cool which will be fun to work on, useful
to people, and will benefit from being on a portable platform.
