Disclaimer: I'm the author of it.  I don't intend to be defensive,
BUT here are my thoughts...

I don't think you're going to find something simpler.  Everything but
the user ID is part of the Quixote session object, if I remember
correctly; you need to persist it in order to have sessions work
properly.  (You can discard the user ID stuff pretty easily.) Let me
know if you find out differently ;).

It's also demonstrably reliable, in the sense of being in several
deployed environments for well over a year now.  I think several other
people are using it, too; no bugs have been reported.

The only module you really need is the session.py file.  The db stuff
is only used for the user mapping.
