We have implemented the core features. Pub/sub is on our todo list. Is pub/sub a critical feature to you? If we support pub/sub, what would be your motivation/obstacle to switch to our product?

I'm currently using redis in a pair of applications, one of which also uses pub/sub. I have many other applications which would benefit from the caching layer that redis provides, and since they currently have none there really isn't an obstacle to testing another solution.
