To clarify further, the MIT Windows implementation of the ccache is not file
based. The ticket cache is kept in memory and is accessed via a local RPC
mechanism. The local RPC mechanism is authenticated. Under Win2k and XP one
user cannot normally access another users tickets.

Not specifically.  A ``ccache'' is an instance of the generic
credential-cache API.  There is nothing preventing one from using (for
example) a UNIX shared-memory segment to store the credentials, rather
than a plain file.[1]

[1] Actually, there is: traditional SVID-style shared memory segments
are persistent, and thus would eventually be completely consumed
unless every user was absolutely scrupulous in running `kdestroy'.
