Quite a lot of work went into your program, I bet you learned some good code while writing it. I've used a simple Windows program called Easy Net Monitor. You can specify IP address or hostname connectivity tracking with email alerts.
Correct, if that machine goes down you won't have any notification. I was thinking along the lines of you are hosting services on one machine while the computer itself is acting as the host or hypervisor.
