Yes, that's another solution I forgot to mention.

Thanks, but I already have the code to dynamically load a module from a 
string. My problem is how to control it, and how we want to do this kind 
of things. Up to know, scipy have never depended on env variables or 
configuration files, so I don't want to introduce this kind of things 
without discussing it first.
