REQ: Efficient object hiearchy comparison algorithm

I've got a hierachy of classes and want to iterate
through two instances and return the differences between
them.

Take the following scenario. I have a class called
Customer. It contains name, phone number etc public
properties and a property that exposes a list of
Accounts. That list of Accounts is an arraylist of
Account classes. The Account class has several public
properties, including an AuthorisedBuyers arraylist
consisting of Contact classes.

Using reflection, I can recursively descend an instance
of this hierachy and retrieve the values of all public
properties of all object instances.

What I'm not sure how to do is compare two instances of
Customer and report the differences between them through
the levels.

Thanks

Ben
