Yes.  That's correct.  TTL I/O with RTS/CTS.

It's true about the speed reduction, but as I'm sure you know additional protocol always comes at a cost.  I think it's worth it for embedded applications.

You could look at the 8-byte maximum data length as a negative or a positive.  CAN was designed for real-time control.  Limiting the packet length adds predictability.  No single device can monopolize the bus for longer than one data frame.  The downside is that you have to break apart larger chunks of data.  Remember that can was designed for distributed control where small amounts of binary data are exchanged.  If your application requires streaming audio or video, there are better alternatives http://forums.parallax.com/forums/emoticons/smilewinkgrin.gif
