Reading from mongodb (BSON)
Now we have a neat read_json function (#3804), it'd be really neat if we could read in from mongo using this i.e. without have to create an intermediary python object.

_I wasn't even sure how to return a json (bson) string from a mongo query, though surely this ought to be relatively easy..._

I've no idea how much of an issue the BSON parts are, or whether these can be converted after the fact...
