Sorry I didn't see this thread before but my "solution" may not be feasible in your case anyway. There is a feature in Windows (and probably on the Mac too) which allows you to control one computer from another one. It is called "Remote Desktop Connection" and is built into all current Windows systems. The only catch is that the computer you wish to control has to run the "professional" version of Windows. The computer you use to control the one that has your records can run any version of Windows. I use this frequently when away from home with just a laptop or tablet. It works on an in-house network and over the Internet.
