We at TDC Tele Danmark offer a residential ADSL product, where we assign
addresses via DHCP to the end users PC's.

The default configuration allow for 2 leases pr. ADSL line, but for a
modest admin fee, we allow for 6 leases pr. ADSL line.

It's really a no brainer, and it dramatically lowered the number of
calls to the helpdesk, the users are happy, no problems with PPPoX or
the limitations of NAT.
