I'd suggest looking at the pkg_resources code, particularly 
find_distributions and its related functions.  Note, for example, 
that egg layouts can be nested (even when zipped!), and that the 
metadata can have different filenames, depending on the installation 
format.  Version parsing also has certain peculiarities, which also 
means that people doing simple string comparisons on the version 
field is probably not going to suffice.
