ok, I'm not sure I completely understand.  If my HS uses stealth auth,
what data remains in the clear?  Is the HS descriptor on the HS dirs
stored using a persistent identifier, or does the identifier change
every 24 hours?  Are there any persistent identifiers that can be
observed on the network to track usage of the HS?  Thanks much.
