Homeplug Powerline Alliance seems to be leading the pack:

HPLA (aka Broadband PowerLine or BPL) has several important advantages:
1) Large number of alliance members and manufacturers, including Cisco (and
hence now also Scientific Atlanta), Comcast, Earthlink, GE Security, Intel,
Motorola, Radio Shack, Sharp, Sony, et. al.:

2) Large installed base both in US and worldwide of low speed products
3) HOME AV high speed standard for multiple SD/HD streams ratified in August,
with silicon soon to follow. Includes DRM.
4) Command/Control Spec is in development to standardize how various household
appliances (HDTV, STB, RCVR, Refrigerator, A/C System, Cellphone???) all talk
to each other.
5) Uses EXISTING power cords to interconnect ALL appliances, not just those
connected to cable coax.
6) No screwey WiFi antenna stubbies poking out of each and every interconnected
component.....or WiFi coverage problems.
7) Uses OFDM modulation.....just to throw Bob a bone....
Hopefully this will eliminate the complex house wiring required to distribute
OTA TV, CATV, SAT, IPTV systems to multiple rooms in the house, as well as from
the HD-PVR "Hub" to individual display systems.

simple...companies without IP in the standard won't adopt it.
