I can talk about one option that *should* be in 1.1: Ruvlets.

Tom Enebo has been working on a nice, simple Ruby-based servlet API for 
folks wanting to use Ruby but not wanting to wire in Rails or another 
large framework (or for people wanting to easily wire framework X into a 
servlet environment). It goes something like this:

ruvlet.rb:

   def service(request, response)
     # handle request, send response
   end

And that's about it for the simplest case. You stick this in a WAR file 
with the Ruvlet servlet configured, and it will be routed all requests. 
There's increasingly more specific mechanisms for wiring things up too, 
from specific HTTP request types to basic request routing to different 
scripts. But it's nice and simple, with no cgi.rb overhead and with a 
choice of dozens of high performance WAR-based server front-ends.

I'd love to hear if people are using JRuby for the others. I know 
Camping works, but I don't know if there's any major JRuby Camping users 
yet.
