Your thought how to encourage one-shots that are not planned days in advance to liven up the pace and game some with strangers like at the planned convention??? Like when company's have staff run introductory games on roll20 when they come out? Maybe ask some company's to endorses gm's with store credit for roll20 online products in return for running oneshots of their new-game/game? they can treat it as a business marketing based expense and its better than ads for sure and cheaper.... or even simpler give gms their product in pdf so they can run it... or even just a quick start rules, premade characters ,maps, tokens ,sound-effects soundtrack oneshot short adventure and audio of the game creator reading the flavor text, correct me if i am wrong but the only thing the gm would need to do is read the rules characters and adventure... minimum prep time and still a fully loaded adventure with all the bells and whistles on... the company gets great press and advertising if they invest and we players and gms get a great adventure that otherwise we would have had to work very hard to create... also most gm's dont have the time or expertise as even a small company not to mention the bigger ones who can make something amazing with this if they chose instead of creating pale imitation on the computer games or consoles of the real thing or as close as you can get online... Best part is companys should be begging for the chance to work with roll20 to promote their product for the smartphone generation of instant and complete gratification with putting in the minimum amount of effort... (i dont mean it as critisisem i personally think it would be great to get what we want without working hard for it...)
