Also is this tracked in a statewide database or just at each service center? Anyone know if the inspection machine is hooked up to the internet?

Uprev keeps your ROM ID. They download the stock data, make modifications and then re-upload. You can export and move ROM files around but that is not typically the way it is done. If UpRev doesn't recognize your ROM ID group then it doesn't let you work with it, that is a safety mechanism since there are subtle differences between auto's and manuals, touring and base, sport, non-sport, and all the permutations thereof etc. The ROM ID can change on the manufacturer's whim as well, or to indicate or to indicate a revised ECU between model years.
Yes, the inspection stations are online, typically via dial-up. The information collected by the scanner is sent to MA RMV, you don't get a sticker until the information is successfully transmitted and verified.
