Good on you guys, I am jealous! I'm not in the right frame of mind to do this right now, but this discussion has really opened up some ideas for me to get back the kiting mojo. PLEASE post lots of photos and stories.
My fiance and I both love remote camping (I have done the Bibulmun Track solo and unassisted), I love kiting, and once he is up and going, this kind of thing will have to be on the cards. What an awesome way for friends to spend time together kitetouring!
I did a downwinder from Eagle Bluff (I know what you mean by sketchy launch on the south side stevabeva!), to Denham, and it was a fantastic day, seeing coastline you cant get to from land, and all in the silent power zone of kite crusing. How glorious to do it for days on end.
Enjoy

I will have to learn to harden up a bit though- camping without a being able to rinse off the salt water and cold beer at the end of the day will be my biggest challange (I am a girl...)
PS that kite shelter posted by Andy was mine- was a good idea, but not really practical if a)no wind (needs wind to keep it up), b)too much wind (keeps pulling even huge sand pegs out of the sand)
