Hi Denny, There is nothing wrong with dividing the workload over a couple of PicMicros. Although I am no mission-critical embedded application specialist, I do happen to know that they split a lot up into small dedicated parts when it comes to certain mission critical applications in the field; like in modern jets (military and commercial). There is nothing wrong with using something more powerful. This is probably a perfect opportunity to get started on something bigger, badder and louder!
