Yes, Agree we should not change the users machine binaries, we should use
the docker client of our vagrant box only. Any one having detail understandings
about vagrant connect? that can be used. I am not expert with vagrant, so going 
through those thing. I believe that would be our solution to this problem.

One remote api call machanism would be enough to handle this I believe.

Please let me know where I can get a detail understanding of vagrant connect command how it works?
