The class registry you showed had keys and values. You can register different utilities for the same interface by providing a different name for each one (I think of this as a namespace). You can then get all of the utilities for that interface with getUtilitiesFor. From docs: >>> sorted(components.getUtilitiesFor(tests.I2)) [(u'', U12(2)), (u'three', U12(3))] In that example, ``components`` could be obtained as follows: from zope.component import getSiteManager components = getSiteManager() Is that sufficient?
