the nightmare way:

create several lists, called, for instance, "only-in-A", "only-in-B",
"only-in-C", "in-A-and-B", "in-A-and-C", "in-B-and-C" and
"in-A-and-B-and-C". I think the names are self-explanatory.

Then, subscribe "only-in-A", "in-A-and-B" and "in-A-and-B-and-C" to
"listA", and all B-related sublists to "listB", and so on.

If you have a web form to handle subscriptions, that should be easy to
manage, otherwise it will be a nightmare.
