Using TFS with Xcode

After some searching, it seems our options for integrating Xcode with TFS are pretty limited. Currently Xcode does not provide an API or plugin model to support SCM using anything other than CVS or Subversion. Although it seems straightforward to set up a subversion server and connect to it with Xcode, it would of course be ideal for us to integrate with our established TFS environment. The top recommendations for what we are trying to do are Teamprise (standalone UI) and SvnBridge. SvnBridge seems to be our best bet, acting as a layer on top of TFS to make it appear to be a subversion server to Xcode. Although it may not be the ideal solution, it could meet our basic needs.
