Yeah, it's interesting to see which parts are in Rhino and which are in 
Scala.  Over the weekend I started working on hacking it into Sakai.  
All the servlet/jetty stuff is in Scala, and I wrote an initial 
ServletContextListener in Scala (my first lines of Scala! ) to bootstrap 
it into Sakai.  And then the Database Configuration is all in Rhino, so 
I was able to modify it to use Sakai's DB there.

It's very exciting.  Since it's originally using mercurial I'll probably 
throw up the SakaiEtherpad mods on my Bitbucket account soon, and 
interested folks can hack in.  For an initial demo we can put in some 
hooks to various parts of Sakai, and just start with a basic 
ContentHosting Resource type.  And then add more interesting hooks going 
forward.

What an exciting OSS release!
