[Twisted-Python] can pb.Copyable objects be compared for equality after a round trip?

[Micky Latowicki]

It's possible to make each element in the set being edited a
cacheable. If you think that would introduce too much overhead, then
you can add a method to the "address book" object which updates one of
the entries in this address book, and uses an id to identify the entry
within the address book. So the address book is the dict. That's what
I did in a similar case. I'm no expert though.
