Could identifiers help with this issue? In the commercial book world we have ISTC, which identifies a textual work. This is distinct from the ISBN, which identifies an edition specific to a carrier (or a "container", as we're coming to call it). ISTC merely identifies the string of text, independent of the carrier. So one ISTC could have many ISBNs related to it.

It's a lot less rigid than FRBR - less hierarchical and more "webby".
