Not yet, but I'm working on such a project. To keep the reliability high 
and the CPU workload low I had planned on using a CAN-capable 
microcontroller on a small daughter board that I'd talk to using the 
high speed serial port. That keeps the software on the Gumstix very easy 
to write and use, and the microcontroller can buffer a bit (although I 
had planned to slew the CAN bus to a slow rate anyway, for higher noise 
tolerance - I don't need speed in my application).


There are Atmel microcontrollers that support 1Mbps serial and CAN 2.0B. 
They're relatively inexpensive, small, and easy to use.
