ATM there is not much documentation on this. Have a look at the 
sling-scala code at http://code.google.com/p/sling-scala/ to get an idea 
on how to integrate a new language with sling. The code also documents 
the classpath problem with the Scala compiler.

I have a working prototype in my private sandbox. It focuses mostly on 
getting the Scala compiler to work at all. That is, resolving classes 
without having to provide a hard coded classpath. I will need to do some 
cleanup/fixing before attaching it as patch to 
http://issues.apache.org/jira/browse/SLING-549.
