Well, I'm thinking  of it using ARMs mostly as master devices using LIN 
slaves for remote sensor/actuator.  Although I do have a case where 
reducing the number of connections is a big plus and the amount of 
communication is small so....

Have you read though the LIN 2.0 spec?  I just recently got it.  I had 
previously been through the 1.3 spec at an earlier job.  They have updated 
the higher levels in particular.  The LIN spec very nearly weaves itself 
into the application layer.  I can see where that would be quite useful 
when you are integrating multiple third party slaves.  With proper tools 
the complete network interface would conceivably be built in a matter of 
minutes.
