Question: Have you experience with it on heroku? Does it work well there? Any difference between its behavior and the "normal case" of RoR as far as what heroku is designed for to your knowledge?

(Like I've said, got nothing about ruby, just don't feel rails is a good fit for the stuff I do; something lighter weight like this could be a good substitue on heroku).

I haven't, but I know it works fine. Heroku is more of a Rack host than a Rails host, so any Rack-based framework (AFAIK, all Ruby frameworks at this point) run seamlessly on it.
