There is a lot of history to this sort of discussion. Windows 95 was supposed to have an "object file store" as was NeXTStep v4.0 ... I think the basic idea was you would have what we now call "tags" for each document you worked on; everything would go into a datastore similar to what we now call "NoSQL". A "soup" where you just pull out the document(s) you care about. Earlier discussions on this subject usually got into ideas like "pointer swizzling", virtual memory management, mmap'ing such files, etc. as the way to actually implement such a document store was considered.
