Suggestions for my use case

Hello,

I've been tring git for a few private projects and have come up with a way to organise distributed development on multiple machines. I was wondering if anyone else could comment on what I've done? Here it is...

I want to be able to work on a project called proj on multiple computers, and have backups on removable media. Let's say I have computers c1 and c2, and a removable hard disk labelled disk1. I've setup the repositories in

  c1: /home/me/proj
  c2: /home/me/proj
  disk1: /media/disk1/me/proj

In c1:/home/me/proj/.git/remotes/c2
  URL: ssh://c2/home/me/proj
  Pull: refs/heads/master:refs/heads/host/c2
  Push: refs/heads/master:refs/heads/host/c1

In c1:/home/me/proj/.git/remotes/disk1
  URL: /media/disk1/me/proj
  Pull: refs/heads/master:refs/heads/disk/disk1
  Push: refs/heads/master:refs/heads/host/c1

In c2:/home/me/proj/.git/remotes/c1
  URL: ssh://c1/home/me/proj
  Pull: refs/heads/master:refs/heads/host/c1
  Push: refs/heads/master:refs/heads/host/c2

In c2:/home/me/proj/.git/remotes/disk1
  URL: /media/disk1/me/proj
  Pull: refs/heads/master:refs/heads/disk/disk1
  Push: refs/heads/master:refs/heads/host/c2

c1 has these branches:
  master
  host/c2
  disk/disk1

c2 has these branches:
  master
  host/c1
  disk/disk1

disk1 has these branches:
  master
  host/c1
  host/c2

So after doing some work at c1 and committing into master, I can
  c1$ git-push c2
  c1$ git-push disk1

Then when I sit down at c2:
  c2$ git-pull . host/c1

Or if I've forgotten to push from c1:
  c2$ git-pull c1

Or I can cart disk1 around, and
  c2$ git-pull disk1

Each repository stays on its master branch. As per the git-pull man page, no development is done on branches that I pull from.

This is working fine for me at the moment, which is single person development, straight line, no branching. When I come to branches, I think the branches will need to be added in each repository, with push and pull lines in .git/remotes/c1 etc.

Does this look reasonable? What have I missed that would make this more manageable, particularly with respect to branching?
