Shane,

you don't have to provide special path() to your objects. The PathIndex
works
a bit different from the other indexes because it does not look for an
attribute
or method with a name equal to the name of your PathIndex. So how do
PathIndexes work ?

- ZCatalog calls PathIndex.index_object() for all objects to be cataloged.
- index_object() determines the physical path the object and indexes this
result
  inside the PathIndex data structure.

We have not seen necessity to provide support for a user-defined hook. If
you have some
use cases let me know.

Hope this helps ;-)
