Yeah the international tech standards are woeful. Look at Caller ID in the telecoms world, it uses a dialup modem protocol, so what can you do with a bit of hardware that can handle that, I'm thinking hardware that moves landlines onto computer based phone systems? Reprogram some firmware perhaps? Then maybe you have a dialup modem instead of some PSTN to ethernet device? Its fun looking at the hardware, wondering what else a component can be made to do besides its obvious legit function.
