The ModIO's primary purpose is to be a pendent interface:

The example above was my attempt a bending it to another or more generic
purpose, but shows basic issues to use it with EMC2. Once the
application is sorted out, it should be easy to duplicate it from then
on.

Another thought, a component or hal sub-file could be used to objectify
(grouping existing components) a "standard" pendent, short of connecting
any hardware. It would be up to the integrator to hal link the hardware
to the object file. I'm not sure if that helps or not.
