I'd like to point out an error in this article. Worldcom/UUNET is not presently using PPPOE, at least for its business oriented DSL. The reasons are numerous, but UUNET SDSL offerings include static IP addresses, which nullify the DHCP issue. The layer 2 protocols that UUNET uses depend upon the CLECs, but there is not currently PPPOE implemented on UUNET SDSL.
