In general, for analogue output it does seem that
caching is probably the best way forward. However, there are 
situations where queueing rather than caching would be required.

eg:
An mbbi output requesting processing through a sequence of states
   this could be as simple as a device that needs to be switched 
   off the on again in oreder to reset it.

Taking backlash off a motorised component.
   or any other device where a transient peak was required.


Perhaps some mechanism similar to the deadband used 
in ai records could be used to discriminate. 

Pete.
