I'm just going to pop in since there is all the talk of ROI and individual payouts. I'm nobody, a lurker, a miner. So these are just thoughts from a semi outside perspective.

The idea that was behind this thread and the thread title are outstanding concepts. The idea of multi-sig fund management is an amazing concept, it starts to diverge when it becomes a group buy scenario. Group buying mining units, group buying hosting, escrow for purchase, a different escrow for hosting. It holds a lot of trust in certain individuals, unless this is all part of the OP post 4-6 multi-sig account as the escrow holders, but I see no mention of that specifically, perhaps it is just assumed.

The idea of a true mining co-op is astonishing. Incorporated as a mining firm, with eyes set on the future. Elected board members from across the world using multi-sig funds to conduct business on behalf of the co-op, with individual hash power as voters in the incorporated co-op business. Elected members donating time to the duties of the co-op to better every share holder, think secretary, treasurer, business manager.

Moving beyond individual ROI to the betterment and growth of the Co-Op and reinvestment of funds to expand, both in mining capacity and revenue streams. Building out or implementing blockchain related services (driveshare storj, micropayment systems, own datacenter/hosting).

Shares can be bought and sold, and include the voting rights, with additional expansions adding shares. Share holders would receive small profits from the additional sales and revenue on agreed upon time segments.

Voted upon bylaws and directives. A miniature bitcoin system with consensus, share holders deciding what is best to move the Co-Op further along, or flat out end and split revenue.

This is somewhat how my electric company operates, they have a semi monopoly on the area of course, but every user is a voting member of the co-op and extra profits are sent out every few years (it amounts to nothing $23 since 2006), but the larger users get a larger portion, and we all have voting rights at share holder meetings, and each have a vote on our board members.

I just think, if you are going to go for, go for. If you are putting your money into something just to get a few dollars off, that's thinking of the short game. If you are investing in yourselves, this technology, and the future there are many paths to choose. Starting a co-op that could become a payment processor for the future, a data center for the next generation, and at the same time increase revenue while cutting costs is a titillating idea.

It's late, I'm red-bulled up, I apologize.
