This is exceedingly cool. It could be a modern-day Lisp Machine that takes advantage of the Linux kernel's great hardware support. Since Python is such a dynamic language, I'd be interested in how they plan to allow the Python processes to communicate. This would be a great opportunity to avoid the classic Unix mistake of using text files as the lowest common denominator everywhere; a structured data format like S-expressions could be passed around instead.

Edit: Other languages I'm thinking of for this idea:

* Lua or LuaJIT (even more dynamic and really great performance; smaller and somewhat fragmented ecosystem)

* Scheme (potentially also fast and good S-expression support, also very dynamic; small and very fragmented ecosystem)
