If what DNS*W*Ls do is of any interest, I can write about how the Habeas
Safelist operates.

For the sake of this discussion, let's assume that the receiver is not
keeping a local copy of the Habeas Safelist and is querying a Habeas
accreditation server.  The input is a reversed IP address.  If the IP
address of interest is 1.2.3.4, enter the following command:

host 4.3.2.1.accredit.habeas.com

If the IP address 1.2.3.4 is included on the Habeas Safelist, then the
accredit server returns a response such as the following:

4.3.2.1.accredit.habeas.com has address 127.0.0.20
