I've decided on the last date to donate: >1 BTC donations before or on September 2nd will get the beta!
So people who donate 1 BTC won't be getting it on the 2nd? Or do you mean >= 1?
From the OP comments: "Donate 1 BTC or more before or on Septempber 2nd and get early beta access!"
So its 1 BTC or more, I would assume.
I think that is pretty clear and he would not withhold it over a technicality that can be resolved with a single satoshi
