I'm not related to redis devel, but I happened to be at the conference where antirez announced the modules.

My understanding from the talk was:

* already available: strings DMA, that you can use for new data types

* in progress but soon (like, a few weeks): commands pre-hooks, that you can use e.g. for auth

* I assume soon (but I don't recall, it could be already available): operations on new data types

* I don't think I've heard anything about alternate db format, but maybe you can think of creative ways of mixing pre-hooks and strings DMA

* I'm not sure what you have in mind about multi-tenant, but I guess you can implement some primitives in a way similar to auth

What I meant by multi-tenant is a multi-user redis (just like multi-user mysql/postgresql. (ie) i can create users and have them use redis completely separately on a single instances on redis.
