Cool!

I'll add a note: one of the optimizations/tricks we noted while composing
was that a server may actually detect a misbehaving log that it _doesn't_
trust.  Ordinarily we'd discard any such data (because of the
aforementioned problems with DoS and such) - but by looking at the
submitted certificate, and checking if it chains to a root cert in the
store you recognize, you may decide "Actually this one is interesting
enough to keep."  (Still some DoS concerns there, but a trick servers have
the opportunity to work with nonetheless.)
