Brian,
I also do housecalls and have wondered about "taking the plunge" myself, but have been too chicken to try! If cell phone coverage is good in your area, you could log in remotely from your laptop thru a VPN or a service like GOTOMYPC by using a wireless card. Then you wouldn't need to worry about the integrity of your database. I am hoping to try that route soon, but cell service is so spotty here that I am doubtful it will work well.
