You may be familiar with the technique used by Netfind to locate white
pages services - by looking up TXT records in the DNS.  If not, see

I think this technique might be useful as a generic method for
advertising services, i.e. by putting the "official" URL for a service
into (say) the DNS entry for the server which provides it.  This info
may then easily be harvested by resource discovery systems.

Registering your service only requires the addition of a single line to
your DNS configuration, e.g.

  www             IN      CNAME
  lust            IN      A
                  IN      TXT


  # nslookup
  Default Server:

  > set type=txt
  Address:      canonical name =     text = ""

There is scope for putting some more info in here, e.g. brief
description of server, admin contact, whether robots are
allowed/encouraged, ...  I think this is the province of the info
server, rather than the DNS

OK, what do you think of it so far?
