The communication between the PEP-II high voltage power supply system and 
our RF EPICS system will be done in exactly the same manner.  We also use
the 16 bit binary device support and set up the the database using the
same formula as you.  In addition to binaries, we had the need to send and 
receive analog values from HVPS so we developed devABANALOG.c (very similar 
to devABBINARY.c) which provide device support for longins/outs and 
analogins/outs and assumes 16 bit raw values.

This could be added to the standard distribution if anyone is interested.
