Sorry I have closed the PR by mistake. @tomchristie Do you mean to change the current redis backend and use aioredis instead of asyncio-redis? if so, I can take care of it.

Yup.

(I actually meant adding an aioredis PUB/SUB implementation in addition to the existing asyncio-redis PUB/SUB one, but actually let's just change it over competely, as the simpler option.)

Im very interested in this backend. Is there a way to push this forward without forking?

@sarendsen Using your own fork and reporting any issues is a good way forward.
