1kg for a touring tent? I can do better than that :P

If you clamp the breaks on, you just need the fly-sheet. no poles!

you'd probably want a front door, and inner on that mind you...

It already exists. The Topeak Bikamper comes in at 1.6kg.

Doesn't quite seem light enough for me - I got an entire 2 man tent down to 1.3kg for touring...
