[zeromq-dev] MongoDB driver with pyzmq

[Brian Granger]

Dan,

As Min mentioned, this is something we have thought about before.
But, to do this right, you would need to modify the MongoDB code
itself to talk zeromq, rather than http.  Just bridging
zeromq->http->mongodb is much less interesting (but still of some
value).
If you are intersted in going the next step to modifying MongoDB
directly, I would definitely contact the MongoDB devs.

Cheers,

Brian
