Cache it once, subsequent requests (even weeks later) use TCP/IP 
without resorting to DNS queries. The effect for most (individual) 
lookups is the same, even (for instance) after DNS is poisoned.

Hmm . . . but *which* DNS system?

I could sort of see it as a pre-XRI hack to support Tor (which the 
mainstream DNS *doesn't*), but that's hardly "the real world", so 
never mind ;)

No domain names, or strings that look like domain names but *can't* 
be looked up through the usual DNS?
