i think he's seen RFC 1034 :-).  anyway, i don't see the difference between
http://sony/ and http://sony./ and if a technology person tried to explain
to a marketing person that single-token TLD names *can* be used as long as
there's a trailing dot, the result would hopefully be "that glazed look" of
nonunderstanding but would far more likely be an interpretation of "oh, so
it's OK after all, we'll use it that way, thanks!"

furthermore, the internet has more in it than just the web, and i know that
"foo at sony." will not have its RHS ("sony.") treated as a hierarchical name.

i think we have to just discourage lookups of single-token names, universally.
