Yes, but

1. CAN is dying, to be superseded by EtherCAT, XCP etc.

2. CAN requires special adaptors (vendors are IXXAT, Vector, NI), which
have no standardized interface. You need to standardize that interface
first, i.e. do the job sockets did for Ethernet adapters.

3. Raw CAN is only 20% or so. Most vendors use CAN Open on its top. CAN
Open is an utter mess.

4. Raw CAN is useless at the application level, because it has only 8 bytes
of data (if you don't mess with IDs, which would give another 11 bits).
