SmartGlass & Play To Questions

[Skaughtto]

The marketing is a little unclear about exactly what you can do with SmartGlass, PlayTo and the Surface RT:

1) Can the Surface "Play To" a Sony PS3?
2) Can the Surface "Smartglass" a Netflix viewing session to an Xbox 360?
3) Is an Xbox Live Gold membership required to watch Netflix on a Xbox 360 via the Surface?
4) Is an Xbox Live Gold membership required to "SmartGlass" Xbox Music to a Xbox 360?
5) How about for internet browsing?
6) Has anyone tried "SmartGlass" or "Play To" with PowerPoint?
7) Is the Surface more of a wireless controller than a media server when using SmartGlass?
8) Should I just get a long microHDMI to HDMI cable?

I checked this out, but it doesn't really answer my questions about what the Surface can do when paired up with a Xbox and what it can't do without a Live Gold membership:
