Quick Thoughts on STM (Software Transactional Memory) in Scala (Akka, et al)

Judging from the fact that Odersky's new company, Typesafe, is including Akka in their Typesafe Stack means that there must be a growing interest in concurrency, actors, and Software Transactional Memory (STM) among Scala developers. Personally, (and I regret to say it) the only area in which I'm really familiar with Transactional Memory is with regards to database systems. Anyway, after reading up on STM, I think I'm going to try and apply it my next couple of Scala projects.

Does anyone have any novel ideas in this area? Any papers I need to read? Etc?
