JRuby Community Support

We are a small company working on e-learning domain. We are exercising
various technology or framework options to develop our new portal or
web-application on elearning. So the favourites on the list are (not in
any
specific order)

  1. Rails
  2. J2EE
  3. JRuby

So wanted your inputs on the JRuby community support if we get to choose
JRuby framework. Also want to know JRuby advantages. I have gone
through
some of the coolest advantage of JRuby, still want to konw if I missed
something

  1. Threading => Scalabity
  2. Performance 2.5 times faster
  3. Usage of both what java and ruby got to offer
  4. Unicode support of Java etc etc.

Where are you planning to deploy your application - are you doing the
hosting yourselves?
