What, no doors? FIDOnet? j/k, this is awesome! back in the day, I actually used an old modem with an actual POTS phone line (I think I had to leave it on dialtone for power or play with the receiver) that I'd rigged to hooked up to a 1200bps modem on my PC for my old 8-bit. It did work, but the modem for the 8-bit was only 300 baud (~bps), whereas this should be able to operate at the maximum theoretical speed of the computer's serial port. (115k? probably not, but who knows!)
