Hmmm ... that's an, er ... "editorial"? error on my part.  I don't have
a problem rearranging it in template form, and I'll do so (in conjunction
with some of the other issue you describe.)

The point was, we didn't want to delay releasing the software, and we
wanted anyone interested to know that we're trying to come up with a
way to be OSI compliant.
I can see how it would make sense to announce that part of it outside
the license, though.

Good point.  Clause 1 in the QPL covers this much better.  I'll change

Looking closer at the QPL, it makes a much better approach to the
problem, and is likely an adjustment we'll make.

All I'm asking is that the author assure us that he hasn't stolen from
someone else to give to us.  While I understand the argument you have
of "warranty" vs. "no warranty", I don't feel it's unreasonable, and I
don't see how it violates the "open source" definition.

All things considered, we could add a clause that explicitly warrants that
we have legal ownership and the legal right to distribute the work, but I
didn't think that was necessary.

Yes, for the most part it seems very similar, but here's where I see

Our license is designed specifically to respect the rights of anyone
and everyone who codes extensions to the system.  Notice how explicitly
it's stated in clause 1.  I didn't want to leave anything to chance
or interpretation.
This is what I don't see in the QPL.  Otherwise, it would be perfect
for us.
I'm open to feedback, however.

Sans additional input, I'll adapt the license as indicated elsewhere in
this email and post a v0.2 to the list.

I appreciate the input, David.  Thanks for your help so far.
