At my last internship we played a remote game of Werewolf (also known as Mafia). Because it wasn't working out so well (it's hard to play if you can't see the people you're trying to read), we eventually just resorted to deciding who to lynch randomly.
However, problems arise with trusting any particular party to generate an honest random number. Even if they provide a link to a random.org-generated number, there's still a question of whether they kept generating them until they got the desired result.
So, this app aimed to solve this problem, by allowing one to create a permalink with a specific pre-determined time when it will provide the random number. This allows parties to agree that it will be the authoritative source before it has provided the number, and avoid issues of trust (assuming that the host of the app is trustworthy).
However, it's nowhere near done.
