> you need to incorporate, which, at the very least, costs money A nice (maybe impossible or impractical) idea would be to sell commercial licenses with eventual future payments. As in the commercial license states an estimated price and a clause saying that at any time (with some months of notice) the price will be set to somewhere up to the estimated price. If the project chooses an higher price then the licensee is free to not pay. This would also allow prospective licensee to estimate future expenses and the project to estimate eventual revenue.
