I'm very excited about GB. GVM made working on multiple projects already a lot easier, but dependencies are still a huge pain...
I don't know if GB is the best answer to the problem, but at least it's a big step forward and I'll definitely try it out.
Sounds interesting. But please disable debugging on the live version of your projects or put at least a http basic auth in front of it. Debugging messages are not meant to be seen by everybody - http://babynames.cc/
