It seems very, very unlikely. Dividends have been done before. They were how "startups" used to pay investors back in the railroad days. But the rates had to be set in advance. Without preset rates, investors would have to trust company managements not to skim profits (which there are 101 semi-legit ways to do) and claim there were none to return. And while a railroad could predict profits with reasonable certainty, how could a tech startup?
