dep?

hiya folks - just curious if you've contemplated migrating to [dep](https://github.com/golang/dep) from govendor.

To be clear, i'm not here to pressure/annoy/argue. It's more about just collecting feedback on where larger, active projects are at. (If you have tried and run into problems, i'm happy to provide guidance!)

The issue names no files, tests, or entry points. Start by reviewing how this Go project currently uses govendor and compare that setup with dep; the issue does not define a concrete migration scope or completion criteria.
