What is the best way to share things like API keys among a team of developers, anyway? I'm surprised this hasn't been solved already (perhaps it has and I just don't know about it). I know you can share passwords with tools like LastPass and 1Password, and I suppose you could use those for API keys as well?
It'd be nice if you could, e.g., include a gem in a Rails project, get a single key/password/token from one of the team members on that project, and use that w/ a third party API to set all the requisite API keys for all the third party services used on a project. You could also rotate the master password when team members leave the group.
