As just one ambiguity here that adds confusion, lets say your
language isn't exactly scheme. We have precedents for that (racket,
for example) and I've had a not-quite-scheme I've worked on over the
years. Does the license cover it? It only mentions "scheme" after all.

Here's another issue: whose copyright do I put on the copyright page
(other than my own)?

If this was just under some Creative Commons license or what have
you, it would all be much simpler. They've worried about these issues
for years and have clean, unambiguous licenses. (I'd personally pick
an attribution + commercial derivative works allowed license, but
that in particular isn't my call.)

Anyway, I didn't bring the topic up, but as long as other people
mentioned it...
