Looks fine, but using the might_have or Class::DBI::Relationship::IsA
solutions might simplify things a bit.  I've built my own inheritance
stuff with Class::DBI a couple of times, and it was all pretty simple
and obvious except for polymorphism, i.e. if you have a list of IDs for
Activity objects but you don't know what subclasses they are, loading
them is a problem.  I made my superclass override retrieve() so that it
would query to find out the correct subclass and then load that class
and return it, but that's not a complete solution.
