I therefore propose the following - from the next fork, X% of the masternodes proceeds will go into a dedicated multi-sig wallet that will pay a salary to a dedicated full-time professional marketing person.
Hopefully, in time, the price of darkcoin will go up, this fund will be able to employ more than one person, and thus also pay the developers, webmaster, etc.
imho, the time has come to become less bootstrap and more professional.
While it sounds like a really great idea, it's technically the same as doing an X% pre-mine on the launch and use that for this kind of stuff.
If you do this then expect people regularly jump and say: Look! The developer takes his own cut from every singe block rewards! Crucify the scammer!
I think this should be a voluntarily donation. You could set your darkcoin wallet to pay X amount of txfee (on top of the mandatory txfee when that applies) to the developer fund. And you could also set your masternode to pay X amount of it's earnings to that fund. This could be a non-zero value by default (but still manually adjustable to zero).
