The new inverted logic for the VM you describe seems very interesting; I'm very much looking forward to see 2.4!
Redis is already more than perfect what we use it for -- keeping track of stock price data, and distributing it. The size of the DB is known in advance (the amount of stocks does not grow very fast), and the performance is perfect.
Keep up the good job! (And have a nice new year)

I think the main business of Redis is still as an in-memory DB / cache / messaging system and so forth. We have a decent implementation from this point of view, so the next logical step is making it working in a cluster.
On the other side it's really interesting to see what people can do with Redis data model if much larger datasets can be used without problems (at the cost of performances of course... can't be as fast as memory). VM was my first idea, but I need to admit, I don't like the design at this point. This new design can be much better, and we can have it production ready in a few months. So I'm curious about what will happen in 2011! :)
Thank you and have a nice new year as well.
