I think bitfunder would approve it. It would be a company and not a bond. As far as I know there are not any companies currently offering a piece of the pie for hosting services as well as mining and the additional hosting services could give us an advantage for buying new hardware over other mining companies. We do currently have a few 7900 series cards but I am more interested in ASIC mining going foward. Any GPU mining would be just to appease shareholders until ASIC miners arrived.
There is actually a rather good chance Bitfunder would approve it. The line between a Mining company and a perpetual mining bond is rather thin.
Read this link. Then proceed with questions. The reason there seem to be so few companies/securities on the market for this type of service at the moment arises from the collapse of a bunch of securities/companies built on this premise late 2012 which turned out to have invested in Ponzi schemes rather than equipment. It is understandable, they did the math on equipment and found the rate of return on the Ponzis more to their liking. Then the Ponzis collapsed, they couldn't pay share/bond holders and the only people to avoid scammer tags were none but the most corrupt, if any on that model did indeed avoid tags.
If you do this do it for yourself, your company, or some combination of the two. Once you have the business of mining down and the ASIC market has stabilized would be the time to maybe consider a security.
