I was just referring to SDSI's being a naming system, while SPKI,
as orginally envisioned, needn't be. I didn't mean anything deeper
than that, nor do I mean to imply any particular rigor, deepth,
or precision behind my comment.
However, I remain philosphically skeptical about the need for names
in most of these applications. Distributed names are very hard but
not all that generally useful. Attempts to base authorization schemes
on names leads to thing like X.509.
