Would an "origin" field referencing the full path to a different repo location be acceptable (this is what vendor.json does)?

So you would have something like this to "alias" the package github.com/heroku/slog from the location github.com/freeformz/slog.

...
"Deps": [
  {
    "ImportPath": "github.com/heroku/slog",
    "Origin": "github.com/freeformz/slog",
    "Rev": "abcdefg"
  }
]
...

restore would also have to add the other remote somehow and also fetch from there. Maybe it's okay to punt on that though to start?

I think that's a good start. @freeformz

Any progress? @freeformz

@on99 @freeformz Any progress on this feature?

What is the status on this?

I'm not actively maintaining godep anymore. I should update the README to reflect that. I suggest taking a look at dep instead.
