So, building on some recent work with integrating linters and code checkers into python, here's how to configure emacs to give you real time syntax checking of go. Emacs has a great tool called flymake which can parse the output of 'go build' and give real time feedback in the current buffer.

Here's what it looks like in emacs24 with a window for source code and a window for godoc.

And here's the .emacs configuration required to make this work. Hope this helps someone, go's a joy to work with by itself, but a little IDE integration makes for an all-around better UX.
