There are other elaborate solutions to accomplish this, however all of them=
would require a competent IT/Network Person to manage the network.
If we were the ISP, we would look at such a case an an opportunity, and bec=
ome the managed service provider, for a fee (typically a premium), and prov=
ide the service.
As service providers, we all complain about the end-customer being a pain, =
but we often forget that it the the PITA end-customers that give us the abi=
lity to earn our daily bread!.... I think too many of us are overworked and=
providing highly under-paid services for peanuts, where we often overlook =
at opportunities to get premium value as a PITA, and not worth it...
:)
Just my personal two cents,.....
