Can Git or Mercurial be set to bypass the local repository and go straight to the central one?

Using Git or Mercurial, if the working directory is 1GB, then the local repository will be another 1GB (at least), residing normally in the same hard drive. And then when pushed to a central repository, there will be another 1GB.

Can Git or Mercurial be set to use only a working directory and then a central repository, without having 3 copies of this 1GB data?

(actually, when the central repository also update, then there are 4 copies of the same data... can it be reduced? In the SVN scenario, when there are 5 users, then there will be 6GB of data total. With Distributed Version Control, then there will be 12GB of data?)
