I know PDMWorks is the best solution, but we do not want to make the huge investment of time and money at this time.  We are looking at Windows BranchCache that is included with Windows server and Win 7 and Win 8 workstations.  Is anyone using BranchCache? If not, what are you using?  We are about a month away from going live with a remote office and are seeking the best option for file access.  There must be others with branch offices, what is being used to share files and keep control of revisions?
