Jonas: please excuse this, I'm trying to keep it relevant.

Do you have any URLs etc. for the BBB in this context? Could the 
realtime stuff realistically be coded in FPC, or would this effectively 
mandate a distinct target?

Noting Michel's "Linux is a trojan" comment, would the developers be 
confident using the FPC RTL in a (single-threaded) safety-critical 
application? What about the FCL?
