    Do we need access to more than the standard docker hub?  It also seems 
    that this approach will require modifications to the images wanting to 
    use the proxy.

We do not really need access to more than the standard docker hub, but this one
way to solve the problem of the people having troubles with slow networks, the
docker registry proxy method promises to be transparent for the user, the user
will have to modify their docker daemon file to add the registry as proxy and just
pull images normally, I am working to set that up and do a test on our network
right now, once it is done I will be able to tell if it is really transparent.

    I am sure this is true in most proxy setups.
    
    Sau!
