Ed,
Forgive me, but you didn't answer my question. How do I tell my credit
card company's billing system which harris.com to use? What keeps my
data entry from becoming ambiguous over time?

Eliot,
that's easy. Your credit card company has a previous relationship with
you and knows which harris.com to transmit to. Possibly, to the harris.com
defined at your root. In pretty much the same way, btw, that the credit card
company can disambiguate between you and any other Eliot Lear.
