Digeo is getting into the HD-over-IP pool with a successful test using multiple streams of HD over fiber-to-the-home:

Digeo, Inc., and Comporium have successfully trialed three in-home IPTV firsts: 1) multi-stream HD DVR on a fiber-to-the-home (FTTH) network, 2) multi-stream SD DVR over DSL, and 3) multi-room distribution of both live and recorded content from an IPTV provider. The trial is being conducted on Comporium’s live commercial IPTV system, using Digeo’s Moxi™ Media Center, which has already been deployed to more than 250,000 homes nationwide on traditional cable TV systems.

I’m a long way from getting fiber to my home (I can’t even use TiVo with my cable provider), but man this stuff is cool.
