I hate to be the one pouring cold water on this stuff but...I probably
should inform the group that there was a patent filed in Oct 2001 by my
previous employee on a titled 'Phone Name'. The broad claim involve using
the DNS to resolve a name into a tel: or fax: URL via NAPTR records.

In a couple of months, it should appear on the USPTO website.

Regardless of the merits of the patent filing, the group should take note of
this IPR.
Have you heard of TPC.INT? circa 1990? Marshall Rose??

Read the RFC's because there may be a claim of prior art here in the public domain.
