Indeed! Lots of Jacdac is not about the cable or the UART-based signaling, but about the service standardization and definitions.

Now if only we could get all these silicon vendors to put Jacdac directly on their current I2C/SPI sensors... It's definitely possible given that basic Jacdac implementation runs on PMC150C with 64 bytes or RAM and 1.5k of ROM, but it may be a hard sell since they seem to like lock-in.
