Perhaps you guys want a bit more info - sorry have holiday brain right now 

Basically, we would have a normal pool fee to keep servers running and to pay our developer to keep it updated at all time.

But what about what is left of the mining fee?

I envision a few possibilities:

Involve the miners to help select project to help fund
Or
Setup a fund that everyone can apply to.

But that would of cause require a certain % of miners to use our pool, as you can't fund projects with love, fresh air and water
