Teamprise has released a new TFS add-on called Teamprise Remote Accelerator.  It is a solution similar to the TFS proxy but is designed for single user remote scenarios.  It functions exactly like a TFS proxy but can easily be run on your local client and polls the server to "prefetch" files so that they are already local whenever you need them.  This can be a significant performance improvement if you don't have a big enough remote team to keep the TFS proxy server up to date.
