Jason; The relay and an indicator light or buzzer is easy -- Grainger or Radio Shack parts.
There are multitudes of monitors for anything -- voltage, current, temperature, water level, switch state, specific gravity (!) that have live serial port output possibly in addition to memory card logging. Once you have data on serial out, it's easy to network it anywhere, including emails and even live web page widgets. Talk to Jim Jarvis at APRS World if you want a custom solution, and also Atkinson Electronics, but it is also easy DIY. It can take a small computer to format and send more complicated data in an email or web friendly form, but there are Linux boxes the size of thumb drives, and the software is all free and open source. If you are into it (or have a colleague that is) you can build your own using Arduino too. Basically, once you have something that can read a serial port, you can do anything with the data it gives you -- beam it via wifi, cell, satellite, what have you.
