This software has been around for a number of years now...maybe Phil knows of something else.
Go to
http://www.interactivetools.com and click on their "Auto Manager" program to see what it does. Cost is $300 and you also get to "interact" with their free Forum. Tech Support is Superb.
Also...Steve MacLellan up in Nova Scotia found a similar program when he was setting up his "Community Car" site. Ask Steve. He's over on Willie Crawford's Forum...
