one-letter domains

[George Herbert <gwh@crl.com>]

I count:
i.net
j.com
(j-dom is j5.com)
(m-dom is m5.com)
q.org
q.com
q.net
(v-dom is v2002.com)
x.org
x.com (x-dom)
z.com (z-dom)

So a lot more than just x.org

Oh, and IANA went out and grabbed all the other single letter/number
combinations on Dec 2, 1993, so they're out of circulation.  As a random
question (I wasn't on namedroppers at the time, if it was discussed there)
why did IANA do so and what do they intend to do with the names?
