The IPO is just asking for way too much BTC, I have a feeling this will go the way of Hosted-Mining and end up DOA unless the initial price gets lowered and is replaced by some money from the actual founder in order to get his skin in the game.
If you run the numbers, this is actually a very interesting value proposition. There is plenty of room for growth considering they will be going live with 1PH when the network is forecasted to be around 3.5-4PH translating to an initial 20% of the network.
@ 20% of the network that's 800 btc/day * 65% for dividends = .0052btc/share per day or .0364/week (around 300%/year dividends over IPO price).
edit... As far as skin in the game, they have already stated they will be adding 20% hash rate out of their pockets with the dividends going 100% to investors until .65 is returned.
