I've been spending a bit of time on another marriage of Python and Lisp- embedding Python in sbcl, along with convenience functions for creating Python objects, accessing them, and so on. My friend Travis Hartwell started this by embedding Python using UFFI- enough to allow execution of a string of Python code- in only a few lines of Lisp. I was impressed and jumped in to help add stuff.
It's too early to say whether he'll want to release this publicly, or just make it a learning experience. We've got the distinct impression it's not of much interest to the Lisp community. Apparently the argument is that everything is so easy to do in Common Lisp, there is no need for a good comprehensive set of libraries and utilities. I don't know about that myself. Still, maybe other Pythonistas could make some use of it.
