Do these Tasks Work on RT?

Hey dudes,

I'm about to get the Surface 2, but I want to check first if it can do a couple of things:

1. Does RT have a decent torrent client that works when the device is 'shut', i. e. covered?

2. Does RT support VPN-clients that allow P2P?

3. Does RT have a fully functional SNES emulator that supports gamepads?

4. Does the Surface support larger SD-Cards, like 64 or 128 GB?

Cheers guys! :)
