Pure Python implementation of MongoDB?

Looking around for a noSQL database implementation that has an ORM syntax (pref. like Django's), lets me store and retrieve nested dictionary attributes but written entirely in Python to ease deployment and avoids Javascript syntax for map/reduce. Even better if it has a context-aware (menus), python-based console, as well as being able to run as a separate daemon task. Is there such an initiative already (I can't find it) or should I start one?

There is a Python mongo db driver PyMongo. It is a mongodb.org Supported driver. So its up to date.
And for GUI purpose, there are several experiments going on.

Futon for mongo

This is an old question, so I do not know whether this is still relevant, but I just found this pure python noSQL database that looks really nice:

If you want some pure python indexing and full-text search solution, you could be interested in Whoosh, in some use case, this is completely relevant to use this as a storage.
For both of these, I'm not sure about an ORM interface.
If you started your own solution since then, I would be interested in it.
