I just saw that Loic Baumann posted a tool on codeplex called WIT Synchronizer. It provides two pieces of functionality that has often been requested.

“I’ve made a change to my Process Template, how do I push those changes to existing projects”

“I’ve made some updates to my process in an in-flight project, and now want to update my Process Template with those changes”

I haven’t played around with this yet, but have plans to. I just wanted to get the word out.

Once I’ve played with it, I’ll let you know the results.
