Well. There's still the comediLIB which actually provides the API. As 
long as comedilib doen't change, the kernel drivers can morph as long as 
comedilib does the appropriate abstraction. And comedilib would be 
maintained separately anyway. So, we (the developers) have control about 
that anyway.
