I agree, this will make the box quite a bit larger, but, personally, I 
think it is worth it.

I also do not think that we would only update via box updates, this is 
just a bootstrap. You could still "docker pull" latest. Obviously, we 
would *also* do box updates but not as the only way to update.

I would really like to see us ship a "caching server" of some sort e.g. 
repofunnel or pulp. However, I don't think those are ready yet for this. 
We could investigate adding docker support to vagrant-cachier[1]. They 
are looking for help anyway, but I am not sure how much work that would be.
