Ruby on Rails

Ooo, nice. Yeah, that could solve it.

I also was doing some other research and JRuby completely slipped my
mind. Is that also a reasonable alternative too? Do you guys have any
experience using rails 3 under Jruby? Is it still easy and straight-
forward, or is the mismatch (like getting rails to run on tomcat and
using jdbc, among other things) going to be frustrating?
