Is the Google TV platform Free?
From the Developer's FAQ for Google TV:


  Can I download Google TV? When will it be open sourced?
  
  You can't download Google TV itself, but Google TV hardware
  manufacturers provide over-the-air (OTA) updates. We are working hard
  to open source the code for the Google TV project.


So, as it hasn't been open sourced (yet), and Google specifically say that you can't download it, it looks like you're going to have to negotiate directly with them.
