SONAME for python modules is bad? (aka multiple module version)

[mathieu]

As far as I know there has not been any consensus on how to install
multiple version of a same module in python ? What are the recommended
mechanism ?

I could not find any documentation on the subject. Does anyone sees
any issue with using standard SONAME mechanism when installing a
python module ?

Thanks,
