Using Git in a TFS shop,
Reading Brian Harry's blog on msdn:
http://blogs.msdn.com/b/bharry/archive/2012/08/13/announcing-git-integration-with-tfs.aspx and
Having gone through Ms download page:

It was not clear to me whether I can use Git-TF 1.0 with a TFS which is not on my premises but accessible via VPN.
I am open to a work-around in-case its impossible right now; it should allow me to work independently within a team and not get dependent on some other member to push my Git stuff to the TFS.
Thanks.
tl;dr: Yes, it should work, I use it over a PPTP VPN daily (and it's rare that I'm ever not on the VPN.)
To explain what was meant in that blog post: the Team Foundation Server team makes a distinction between our "hosted" or "cloud" service (Team Foundation Service) and our "on-premises" product (the Team Foundation Server you install on your own computer.) We use the term "on-premises" to mean the TFS 2012 you install even if it's not on your local network, or even in your own data center.
If you're curious, the problem was around authentication - git-tf has no UI and thus can't open up a web browser to require your authentication on tfspreview.com. We needed to add support to the Team Foundation Service to allow other credentials.
This has been done and git-tf can now authenticate to the hosted service.
If you have problems, please raise an issue on the git-tf codeplex site.
