Hybrid jruby/java app w/embedded rails app?

I’d like to package a hybrid jruby/java swing app with an embedded
rails app and hopefully be able to deliver this via Java webstart.

Has anybody done anything like this? Or perhaps point to examples
that implement fragments of the whole idea?

background:

Basically I’d like to distribute a copies of our rails-based system
for dynamically authoring and disseminating Java application
instances [1] to client computers. The Java applications created are
educational math and science activities [2] and are defined with a
declarative xml-based lmarkup that encodes both object relationships
and object state [3]. The delivered applications persist significant
learner data back over the network [4].

One basic user issue is that many schools have bandwidth problems and
having a classroom of student computers start up and all try and pull
20MB of new activity info through one network pipe can cause annoying
delays.

If instead the the teacher (or any user) could download an
application that combined the authoring web app, the Java code, and a
replication framework to synch the data most of the time-critical
data flow would happen on a local network.

I haven’t, but it sounds like a great idea. The only glitch I can
think of would be how a Rails app might respond to being run out of a
.jar, if that’s what you want to do. You might have to make the app
self-extract.
