[ re: DNS reverse mapping ]

DNS is not secure, and isn't likely to be any time soon. Using DNS as any sort of security measure is just plain stupid.

Either the other party possesses the private key material that matches their public key or they don't. If they don't, SSL will fail. If they do, then they're exactly who they say they are (or the private key material has leaked, at which point it's game over anyway). DNS should have nothing whatsoever to do with it. Any modern RFC that makes references to doing reverse lookups in a security context should be laughed out of the IETF.
