Hi Kenny,
I can't speak for Nikodemus, but Screamer+ is just an extension to enable
the logic/backtracking machinery on additional data structures. It still
requires Screamer to run.

Long story short, I didn't know about Screamer+ at first, and got
permission to re-license classic Screamer under an MIT-style license
from Jeffrey Siskind.
I've recently been in touch with Simon White (the Screamer+ author),
asking if I could do that for Screamer+ too: it comes with a "do not
distribute or use commercially" license.
He appeared positive, but said he'd need to check with his old university first.
We'll see...
Cheers,
