Google Quietly bought SageTV recently...
Which is "interesting" given what it's core is capable of.
At first glance it looks like yet another media center app, and a somewhat clunky ui.
Under the covers it's very nifty and flexible.
Think of it as all the best bits of XBMC (sage's default Ui is based on an xbmc theme, has the library functions, and very similar approach overall), MythTV (many front ends hanging from a backed), TiVO (intelligent recording / predictive recording if disk is free and nothing is explicitly scheduled), recording HDTV and streaming it to "clients" (1080i/720p), Place Shifting (thin clients on mobile devices to your own private system), and a whole bunch more.
sageTV is also very DVB friendly and multi lingual support is excellent thanks to a strong following outside us borders.
No idea wtf The Cf is planning on doing with it though as it's not very "Cloudy"
