i released the ore.xapian package to pypi a few weeks back, and after a few iterations i’ve got in production on few small applications, its a thin layer on top of xappy to give an indexing framework for zope3 based applications.
its pretty xapian agnostic.. its designed as an async indexing framework, with abstractions for content indexers, content storage/ resolution, transactional flush into the indexing queue, manages reopening search connections, etc.
the pypi page goes into a bit more detail (doctest style).

i’m using it succesfully to index content from relational databases and subversion with a zope3 front end. only real todo is to make the index queue persistent for remote indexers, but to be useful that
would need corresponding support for remote search connections in xappy. unfortunately i don’t have the bandwidth for the latter atm, but the details are here.
