Absolutely none of this is officially supported, right? (It looks very much like "game on, DotCloud", from what you've been finding, though....)

I don't think any of it's supported. Redis will run, but you can't exactly get to it (no TCP routing mesh apparently). It really just seems like they made it really easy to add new languages.

This is because running commands is from a one-off dyno vs. the formation dyno's that have requests routed to them.
