Are the .pyc's usable without recompilation between 'minor'

Yes.
I presume that the .pyc's are NOT compatible
across more major releases (e.g., 2.3.x -> 2.4.x)?
Correct.
Is there a hard and fast rule about compatibility across
releases that I can rely on?
Each Python version uses a "magic", as returned by
imp.get_magic(). Whenever that changes (and it will at
worst change between 2.x, 2.x+1), you need to recompile
the .pyc files.
If you pass it an "old" pyc file (i.e. one with an
incorrect magic), Python will silently ignore the .pyc
file, use the source, and attempt to regenerate the
.pyc file.
