RoR on GAE?

Question

Since Google App Engine will soon full support Java:

Would it be possible to run Ruby on Rails on Google App Engine? Or the limitations imposed by the AppEngine runtime will affect the JRuby implementation?

What about other languages such as Groovy, Clojure, Scheme?

Are there any effort to support .net and C# in JVM?? I think this would create a NEXT level on webdevelopment.

Answer 1

This is already possible. Its not perfect, but I would expect rapid improvement.

Answer 2

It looks like the plan is to support those technologies eventually.

If you can use the new technologies with GAE to accomplish what you want to, I think it would be in your favor to do that.
