In the design I've been doing with the CA I keep running into
a... "design pattern" (for lack of a better term) where I want to
retrieve persistent objects using exactly the kind of registry lookup
that the CA provides.  In the past I would have used a catalog to
perform such lookups with sufficient performance.  

Registering the objects themselves as adapters where I need to do
these lookups would be tres nifty but I don't know how well the CA
scales.  Doing this through the CA would result in a huge
proliferation of the number of adapter registrations.  Does anyone
know how well this scales?  Does the performance of the CA lookups
depend on the number of registrations being small relative to the
number of content objects or users of an application?
