Been using it for years
Been using Sagetv for years and it is great. Got one server in garage with all my sat and terrestrial feeds going in. Got all my live tv, music and dvd/br rips on it. all tv's in house either have a pc with client on or dedicated sagetv media box . watch live or recorded stuff anywhere any time in full hd.. brilliant.
I hope that google bring two things;
1/ full android client for it -surely!!!
2/ full HD integration to think like love film.
