jRuby support

I tried to create this issue on github or look for a place for questions, but couldn't find such a place so I'm entering it here as an issue.

I'm very interested in using couchbase in a jRuby on Rails project for my company. The https://github.com/mje113/couchbase-jruby-client gem works really well, but I would like to use it in conjunction with some of the rails-specific helpers (session store and cache store) that are provided in the MRI gem.

Do you have any plans to publish a -java version of this gem that supports JRuby (either using FFI or wrapping the java .jar files)? Would you consider separating out the pure-ruby parts of your gem into a couchbase-rails gem so that they could be used with your gem or the jruby gem that already exists?
