Thanks for posting, this looks really interesting, what are you using this for at the moment? I expected a hosted service like IFTTT, instead of having to run your own server, which takes a lot more effort/expense in the long run.
Re your installation instructions, doesn't go get already build and install your app? Just this should be enough:
go get -u github.com/muesli/beehive
then you can run beehive --help. Install took quite a while on my machine, presumably because of dependencies, perhaps it would be worth using plugins eventually so that bees could be distributed that way?
