I was toying with a few ideas, and discovered that I can actually store in a persistent manner references to other persistent objects !! ... This is nice because it allows to point to an object without using paths and traversal (So it's quick and dirty), and the reference is maintained through a rename.
I can see some problems related to security, such as if traversal is not used, then some security can be by-passed ...
Effectively, the same object resides then at different places in the Zope hierarchy. This can be very confusing: We used Shane's "symlink" product that has similar properties. A colleague was able to delete the complete ZCatalog content by deleting an object containing a symlink. The deletion caused a recursive "manage_beforeDelete" which followed the symlink and unindexed all objects referenced from the link target. Similar things may happen with your "multi-place" objects (especially, "catalog"s and "acquisition" may work inconsistently, depending how you access your objects). -- Dieter
