Hi Steve,

This is a good question.

 From a pgRouting perspective, unless you want to implement the 
algorithm in pl* languages, you really have to use C/C++ to implement 
server extensions. And given the potential amount of data that needs to 
be accessed and temporary data managed, this is the option for performance.

 From a pure can it be implemented in Python, there are no constraints.

shows some possible implementations.
