Ah, I see.  For the use cases I'm interested in (HTTP based,
obviously), requiring DNS modifications is a major barrier to
adoption.  I don't want to create practical problems in an attempt to
resolve philosophical differences.

Both trust and authority are highly application specific: can we
simply defer questions about trusting DNS vs http://.../site-meta to
individual use cases for site-meta?
