Forget 200Mbps powerline home networking -- and don't even mention your poky 85Mbps setup -- because industry leader DS2 has just made all current gear obsolete with its introduction of technology that will enable 400Mbps theoretical speeds over standard electrical wiring. Capable of pushing five simultaneous video streams, the zippy new tech will be key for applications such as PVR networking and multi-room HD IPTV, and should start appearing in "next generation" devices slated for 2009. Luckily 400Mbps products will actually be backwards compatible with 200Mbps gear according to DS2, meaning that you should be able to reuse some of your existing adapters and extenders instead of relegating them to the gadget graveyard.
