Nice idea, however be aware that GLBSE is using Bitcoins _only_ but you pay this contract in GBP (which is far from USD parity btw). It might become impossible for you (and shareholders) to track whether my 1 BTC share should be worth 1 share (because I bought it at a price of 20 USD/BTC) or 2 BTC (bechause I bought it at a price of 40 USD/BTC) or 0.5 BTC (because in the meantime, a BTC is only worth 10 USD). You might burn or overrate initial investors, depending on the Bitcoin rate.
Yes, have taken the consideration of GBP to USD to BTC. For USD it is about $24k which is needed (at 1.6). That is why I said 3000 @ $10 and 1500 @ $20. That is over what is needed, but would cover costs if less, and I'm sure that the extra could be used for renting of other machines from valdimir.
What you could do, would be to NOT hand out any shares, until there are enough buy offers to fill the contract. Then on day X release all shares, which are immediately sold, cash out and everyone's happy, because everyone has paid the same value in USD per share.
That would be nice, but offers are sometimes never paid up. I guess, there could be something in the contract that, if not enough shares were sold, all money would be returned via a dividend payout.
Just make sure there is no confusion what this is - it seems to me rather like a fund than a company, meaning even though 85% of the money generated is paid out to 100% of the share holders, it is still you who has ultimate decision power as the manager, I guess.
Actually yes a Fund is a better word for it.
I guess in case the Vladimir contract goes south, you could just get as much money for this as possible, convert it into BTC and pay it off as final dividend - currently there's no way I know of for a shareholder to really identify himself/herself to you in a secure way, so hardware could be sent via mail or so.
Yes, that would be the main option. All hardware would be sold, and company(fund) liquidated back to the investors.
