Nice article. As for keeping stable dependencies while remaining go get compliant - I opted for a slightly simpler solution. We fork dependencies to our internal git server (gitlab in this case, sometimes we just keep our stable fork on github), and go get them from there in the build process.

It's not much different, in that it still requires rewriting the internal imports of the libraries, but it doesn't require copying of files or working with git submodules, and provides the same stability.

I think godep certainly looks promising and I have it in my TODO to try it out, but working with forks for the relatively small codebase we have is enough for now.
