Orleans framework for cloud computing

I've been working on a project in Microsoft Research that builds on some
ideas from E and related work - promises, turn-based execution,
object-capability patterns, etc. It is a framework and runtime for writing
distributed applications to run in the cloud (and eventually on the client
as well). It also includes functionality such as optimistic lightweight
transactions, transparent persistence, and object replication &
synchronization. We're not yet ready to release the code externally, but we
have published a technical report and an online video describing the
project. I'd be interested in your comments.
