Hi Mike,
Since you are planning to use a micro anyway, and it doesn't appear you will 
need a great deal of external logic, you might consider one of the micros that 
has some programmable logic on board.  Cypress PSOC is the prototypical example:

They have a wide variety starting with Cortex M0 and going up, with varying 
amounts of programmable logic.  Their tools are pretty nice, too, with 
pre-built modules and also allowing you to drop into raw HDL if you need or 
want to.  They have a nice selection of reasonably priced dev boards to get 
started.

assign them tasks and work, but rather teach them to long for the endless 
immensity of the sea.
