(I'll comment on the rest of the proposal later -- have to think hard 
about it and don't have time or caffeine to do so now .  Just wanted to 
give a brief comment on this.)

I have an OC_PythonString implementation [that needs some adjustment in 
light of Ronald's recent improvements] that does not convert the Python 
string and maintains the reference to the string.   It works as you 
describe for both unicode and python strings, naively assuming that 
python strings can be represented within an NSString without problem 
[so far so good].

I hope to clean it up and commit sometime soon.   If you are going to 
dive into this stuff, I'd be happy to throw you the source...
