Re: Eyes to the horizon: A bitcoin ASIC project will be announced in June
Seeing the pricing you propose for 1TH in model B (1,000-1,200BTC/TH/year), I'm afraid your IPO price will be too expensive. I would take into account that Bitfountain's IPO price was 0.1BTC per share, for an expected deployment of +250TH. If I do not recall it wrong, each share is 1/400,000 of the total profit/hashrate, which means that their price for TH was 160BTC, not a hefty 1,000-1,200BTC price tag.
Even at today's difficulty, a TH would take about a year to earn 1200BTC. Ridiculously overpriced, especially as that price only leases you the hash rate for a year.
At today's difficulty, 1 TH/s will make 1200 BTC in 27 days. (without electricity costs). You know, 1200 BTC per 1 TH/s is 1.2 BTC per 1 GH/s. Similar price as Avalon #3
Maybe that is why you want to sell shares 
Or maybe you want to sell shares to finance the infrastructure roll out for hosting another 900Thash...I would prefer Mode A, but in addition I suggest you spread your risk by selling some chips or miners too. This will also be good for bitcoin itself.
You say you will pay out 100% of profit, but how do you calculate "profit"?
