maybe it's a good idea to use the same pattern as other distribution/ 
packaging systems.

so foo2 or even foo21 is ok if you compare it to the name 'python24'  
in macports or ubuntu

so that means that any incompatible version results in a new package  
name, so one could be shure to have a compatible version of deps e.g.  
using things like zope.interface.20 without any version restrictions.
