one of their users had their own leased line OR dial up port phone number

run by the user while they are connected is not important due to the STATIC
IPN (Something that would NOT be possible with a dynamic/random IPN
number). Until Dynamic DNS is out in the field, Dynamic IPN supports ONLY
Access not Connection (and as I noted, Demon sells Connection not just
