I mean that a common interface for the average computer would be through
an ELM327-compatible device, which itself is plugged into the OBDII
port. I accept that it's slow, but it seems a good target for an
initial pass. My Dell laptop doesn't have a CAN port accessible.
Thanks for helping me clarify.

I would hope to write something which could connect to CAN in the
future, but present the same interface to a client. I believe this to
be like gpsd supporting different binary protocols. An embedded
computer may present a CAN header, and it's on my wishlist.

Limited by the device, sure. For something like logging speed against
position, 1/s isn't so bad. I accept I won't be polling 80 PIDs every
second.

I appreciate your answer.
