That is good to have. I think there are some work done 
for the 18F452. Check out the QuikBug monitor from
http://www.picbook.com. It will be even better if Microchip
could release the on-chip debugging protocol for 18F
and dsPICs. It would be even better they can release
the protocol of ICD2. But this will take time if it
would happen at all.

Hopefully there will be better tutorials for MPLAB simulator
(for Windows) and gpsim (for Windows/Linux/FreeBSD). I think
there are quite some power users who can do this really well.

By the way, Scott is working on dsPIC port of gpsim. Another
thing is that piklab is now improving by day and it can
support ICD2 programming (and soon PICkit 2) reasonably
well. The author of piklab is also working on the ICD2
debugging support for PIC16F under Linux.
