I'm fairly new to Git, so I may be misunderstanding, but we do have a remote, but that only holds the code that is commited and pushed doesn't it? We develop using local repos, so any code that I've modified, but not commited is only local to my machine, unless I'm misunderstanding.

It's more for backup purposes. I want to be able to export any files that have changed to a network location so that if something happens to my local file system, I've got a recent backup of my changes. I don't want to copy the entire workspace as it's a large number of files, I just want to be able to copy the files that I've changed/added.
