Using classes like Qualifier and SortOrdering one can trivially
implement an iTunes-like table with search and sorting based on
selected column. OK, it's database like, but it also works in memory
on collections of objects, you do not have to have an adaptor, an
editing context and so on.
At least you don't need EOF for this any more. My BDControl
framework includes BDQualifier and BDSortOrdering classes that should
be drop-in replacements for the ones in EOF.
I wrote them so I could write a rule engine for Cocoa applications to
use. (Qualifiers are required for a rule engine, and the use of
qualifiers and sort orderings internally made doing things like
looking up and sorting candidate rules *really* easy.)

Both frameworks are Open Source, under a BSD license.
