Private coin trades are all fine and dandy but you are basically wanting someone to speculate with your money?
Two of the things you mentioned sound like investing with no short term gain and the other.. Riding alt trains does not make sense unless you mean hold the coins and see what happens (speculate again).
Might as well have the admin send it to satoshi dice once a day to see if we can double the profit or nothing... i highly doubt users will be happy with low payouts for a month in speculation of one of your ideas will pan out three months from now. They will all leave.
Multipools organically involve mining and trading.. Having someone in charge who creatively makes more than what simple autosell scrypts do is an asset. Its too bad that MC H20 hasn't devloped his front end and communications to match his backroom dealings. The secret nature of MC is what kept many here; however being too secret when the house of cards is falling is either cocky or naive when Kilotons are leaving in droves. Who knows, the weight of that amount of hash power may be more of a hinderance than a benefit to the long term pool survival? This could all be planned for all we know.
My other ideas are more launch point thoughts into where I see mining evolving into.. Imagine two rigs... One that pays the bills, and the other focused on only coin ipo's, alt-trains, and coin business investments. Both serve a purpose and have different return upsides.
