Well, potential markets:-
ISPs:
Just about all ISP's offer a privacy service on their domains at extra cost.
Nominet seems to play fast and loose with releasing this private information so there is a market to be filled there.
The ads on google under Private Domain also tell a commecial story
private whois is another angle given that everyone at zdnet (is it?) seems to be constantly snooping and stealing your registrations before you get round to it.
Rock Bands
you could hope that LA's private domain get famous!
Other wilder thoughts:
Escaping from the press, bordellos, etc
There is a need for privacy sometimes I feel!
OV is not high so not much natural value.
I'd put it at maybe low xxx
Much higher obviously if you could convince an ISP of it's benefits.
