One of this year's
Golden Cobra winners was a web-based tool enabling remote play & card driven setups. This would work great for rapid-prototyping deck & oracle based games (first example off the top of my head would be The Quiet Year). Setup is done by dropping a list of cards into a google doc and then passing a link to the doc into the website; this also creates a persistent link for everyone, bypassing the need for a screenshare.
Some fancier formatting in the sheet can display different prompts as time passes (including different prompts to different players - already thinking how this could be used for a Murder Mystery Dinner Party),
I'm sure there would be all sorts of other uses, including perhaps prototyping board games, so passing it along!
