Uh, I'd rather finish my prototype first

It's everything -- everything gets a 160-bit handle to itself, as if
all nodes are coexisting with a shared memory.

Yes of course; SHA1 is adequate for all practical purposes: the
collision risk is small enough.

As does Mainline DHT.

ILP, as a specification, needn't mandate implementation-specific
details. As long as its agnostic to identity strings, using the
20-byte hash in an implementation would be equivalent to referring to
an object by a memory pointer, while using the string would be
equivalent to passing objects in some kind of marshalled form. From
outside of the implementation, there should be no difference.
