And we're dead in the water already. That's a typical non-commercial
clause, which means it's destined for non-free at best.

OK, although I think a sneaky lawyer could argue that source code doesn't
need to be provided for modified versions, as the 'provided' clause could be
taken as being the sole proviso on modified distribution. This licence
wasn't written by a lawyer, was it?

What the hell is this? If it's licence text, it's *weird*. Smells like
some kind of preamble or something.

Is this something that the modifier is supposed to affirm or something?

All of that seems OK. The wording on "alter it and redistribute it freely"
is a bit nerve-wracking, though -- that 'freely' could mean 'without
charge', so the phrase could be read as "alter it and redistribute it
without charge", which would be NC again. Also, the permission to
distribute modified versions isn't *explicitly* given. If this copyright
holder plays the UWash game, it's suddenly too-non-free-for-non-free.
But, I guess it doesn't matter, because the first clause of the first
licence is non-free anyway.
