stochastic-technologies/goatfish - GitHub. Looks interesting, a small Python module that uses SQLite as a persistence layer for arbitrary objects. Not at the level of an ORM, but rather at the level of a more complex key-value store. Quite interesting for the usual small hacks where you need object persistence quickly, but due to the simple structures, you don't see much sense in a developed data modeling - or if you don't know yet how the structures will look like during prototyping.
