Based on a quick read of the patent, it sounds like what they've
patented is the combination of:

1) DNS search paths,
2) An HTTP/HTML interface to a DNS search mechanism, and
3) Doing multiple DNS queries in parallel rather than in series.

Sucks for other people in the registrar business, not clear that
anybody else cares except as a matter of principal.

See http://www.hactrn.net/hacks/chives/ for prior art on DNS search
paths (and don't laugh too hard, it was my first large C program...),
not that I think it's particularly relevant given (2).
