You upgrade a remote branch by passing the remote address directly to
upgrade, like this:

  % bzr upgrade --dirstate-tags sftp://bazaar.launchpad.net/~user/project/branch

As for network performance, all current formats use the same repository
backend (knits), so as I understand it their performance will be similar. 
Said that, dirstate-tags still means a (small?) improvement because of
the way the list of revisions is stored (only a pointer to the tip is
kept, instead of a full list of revisions).

The real improvement will come with the new pack-based repository format, 
which is work in progress.

HTH,
