Yup. I'll snip all the agreements furtherdown, b/c it seems we're in
100% agreement here (I promoted your post to the Front Page of the Swiki
:-)).

I was comparing development speed of Java/E vs. Squeak/SqueakE. Just
wanted to mention that we could be quite comfortable with having mostly
everything in Squeak at the beginning, because it will be relatively
easy to move Squeak stuff to SqueakE, as compared to moving Java stuff
to E (duh).

Well, the SqueakL says that you may re-release Squeak under a license
that is ``not less protective of Apple's rights'' (roughly). Saturday, I
loaded the X11 fonts into Squeak, reviewed the licenses that come with
the fonts, and immediately unloaded Lucida again ;-). Then, I proceeded
to remove all references to the Apple fonts, replacing them with
references to Helvetica. After some hacking and garbage collects, I have
an Apple font free image. 

So, I set out to write a license that protects all rights of Apple, but
removes the font clauses. The second bit in the license is the export
clause, but as the export clause is not protecting Apple's rights, I
felt I could re-word it. The end result is the CleanSqueak license,
which I still need to show to a few people (including OSI), before I'm
sure that it is Open Source Definition compliant. That's the best I can
do, given the terms of the original license (and given the fact that
Apple is not willing to re-license Squeak under the APSL - just got that
confirmed last Friday). 

It's 'MIT' for most of Squeak, but 'GPL' for the VM, basically. I think
that's good - you must make available source code to any VM changes,
which helps in keeping the core compatible. 

FYI, here's the whole thing. Note1: unreviewed by anyone. Note2: this is
probably not the most appropriate place to discuss it.
