It would be cool if you could add support for Carthage.

Happy to accept a PR for this. I don't use Carthage myself, so I wouldn't be the right person to add support for it. Also, peertalk is probably best built as a static library (since it's tiny and the cost of loading a dynamic library would be significant in relation to what it does.)

Unfortunately Carthage only supports frameworks. Will create PR soonish :)
