Here's an interesting problem -- in the world of DC comics, there
exists no time T in which Superman and Clark Kent both exist
simultaneously, and as a corollary, there exists no person P such that
P is both Superman and Clark Kent.  On the other hand, there does
exist a person who is always *either* Clark Kent or Superman.  

Does this constitute identity?  If so, then I'd imagine that the same
IP addressed used serially for foo.com, bar.com, and foo.com again
also establishes the identity of those domains.

All the best,
