The California PUC has approved local phone competition within California,
with the requirement the phone number portability (between carriers) be
fully implemented as soon as possible. Making your phone number stay the
same no matter whether you're a PacBell or MFS or TCI customer is exactly
the same problem as making IP addresses portable... just wait until ISPs
are regulated, and they get the same mandate.
Sure...people dial phone numbers...on the Internet, people access
services on hostnames...apples and oranges...
