Cool! I heard of Nagare but don't know much less. I will download it and take a look. Well I wanted serialisation of execution state to help support Long Running Transactions. LRT is a fundamental concept in WS-BPEL. LRT is the motive behind compensation. Since a WS-BPEL transaction may wait an indeterminate amount of time (i.e., weeks for a backlogged order), it is nice to serialise the process to disk and revive it at a later date. This is often referred to as "hydration."

Neat. I use Twisted for my networking needs. Right now, I am focused on implementing WS-BPEL features. So there is stuff for logical ordering (workflow) and scheduling. Unfortunately everything right now is a bit too rough for another developer to use. A challenge for me is to figure out how to create a framework that allows me to build WS-BPEL processors but another Python developer can use for their own purposes

I would say +1 too. However I am content to use Amazon EC2 and my ASUS Surf for my Stackless needs.
