On DSL, no, because the first time your IP traffic touches theirs
is at a router owned by the telco.

On FIOS, no, for similar reasons.

For DOCSIS, in theory yes, in practice no, because traffic
between your cable modem and the CMTS is encrypted. Older
systems used 56-bit DES, which is crackable, but the new ones
use AES.
