I had a look at the changes between releases. The only change in the pickle format is its extension to pickle failed values. The other changes simply reflect the reorganization of the internal class hierarchy of values, they do not affect the format itself.
I will give it a try soon (probably during the weekend). If it works, I will commit it to the svn trunk, and ask people to test it. If testing is successful, I will call for a minor release of Mozart (1.4.1).
