I did this on a project for a Circuit Cellar competition and it proved rather easy. Take your USB and use a FT232BM chip to convert USB to serial. Add 2 optocouplers for TX and RX and connect the other side to the projects serial port. In my case, it was an AVR, however a PIC would be similarly wired. If you lay it out correctly, the worst case isolation is the optocouplers rating.
