Why would you need a PC at each TV? Currently this can be accomplished with an extender for CableTV content and a streamer for everything else. I have a 3 y.o. Patriot Box Office that streams Blu-ray rips with HD Audio. It cost me $60, so the number is more likely $200 per TV depending on what extender you get.
How else are you going to get your media to those TVs through a consistent interface with your TV content.
What is so hard about changing the input on your TV or AVR? This is seamless with the right remote.
Oh, I forgot, WMC is the only DVR allowed to be discussed on this forum these days, and you have to use cable with a cablecard to get your pay TV or you're pissing money away like an idiot, because cablecard is the greatest thing ever, better than having a better selection of HD channels (Satellite) or a more integrated user experience with no DRM.
When you change the input on your TV or AVR, you are switching to completely different graphics, features, menus, color themes, settings, display calibrations, etc. So, instead of having a pile of STBs that aren't related to each other... such as WMC+cablecard tuners (without copy restrictions) + Slingbox + XMBC + Airplay, etc... you can have one powerful seamless multi-client system to take the place of that.

Sounds like a nice idea! At least for those that dont have real sageTV extenders already setup.
