Bear in mind I'm a big fan of Python...

Python doesn't really fit FreeRADIUS well. FreeRADIUS is threaded, and 
Python has the global interpreter lock, which means it doesn't really do 
concurrency in threads very well.

TBH I don't think any of the rlm_$language modules are *that* widely 
used - rlm_perl has it's own problems, rlm_ruby is, well... ruby. And 
unlang or conditional SQL processing solve many of the problems.

I wonder if a better option wouldn't be something like "rlm_unixsocket" 
which passes the request down a unix socket in a standard format, and 
takes the reply in the same way. Then the various interpreters could run 

rlm_rest might be another option.

All that said, the rlm_python code could certainly be improved. There's 
no reason it couldn't present a much more pythonic API (and a much more 
complete one - it should be easy to expose server innards like 
paircompare and so forth).

I might take a look if I get time, but I've got a lot on my plate...
