A shared filesystem based shared replay cache is not farfetched.  A
shared replay cache provider is.

Anyone doing any take-over-the-identity-and-resources sort of high
availability with protocols that use Kerberos will have to deal with
this replay cache clustering problem anyways.

Supporting shared filesystem based shared replay caches is just a matter
of correctly resolving acceptor principal names to replay cache names/paths.
