This is a tricky one. I was just suggesting that while it is clear that 
for wxPython, you'd NEVER be able to run more than one version, that 
possibility should be considered for other packages. I'm imagining a 
module that uses a given package and version for some internal purpose. 
A user of that module may have no idea what packages it is using, and 
may happen to want to use the same package, different version. Unless 
data types from that package are being passed between he two versions, 
this could certainly work.

However, you may be right that this is a recipe for disaster, and the 
user of that module simply needs to test with the version they are 
using,a nd if it fails, get an updated version of the module, so that 
the whole program is using the same versions of everything.
