I have just read the draft as well, and I echo Thomas's comment that it's well written and clear.

One thing I think it needs is some language for future LDP applications.  You define mode-based and mode-independent, and you classify existing applications into one of two buckets.  It seems like a good idea to add some text that requires any future LDP application to assign itself to one of these two categories, so that future apps clearly fit into the existing architecture.
