I resolved this if anyone is interested. I have two physical GBPVR servers that I like to switch between.
For my MVPs, I have installed a Radioshack Plug-n-Power device to cycle the power on the MVP (I use Girder and an ATI Remote Wonder to control it). When I push a button on the remote, the power cycles and the MVP starts from scratch and you can choose another server.
For my client laptop, I have written a couple of batch files that point to a folder I created that contains individual GBPVR Config.xml files for each server. The batch file stops the recording service, deletes the current Config.xml file in GBPVR and then replaces it with the one for the server I want to look at. It then restarts the recording service. When I want go back, I click on another batch file and it switches back.
If anyone is interested in doing this let me know and I will provide the files.
