  From the point of usability I don't know if this is the best approach.  
Maybe adding a "debug code" property to the PIC and setting it depending  
on the code launch method would be better. Your assuptions on the usage  
are good, but you can't know for sure what the user actually want. Maybe  
he wants to load the program on a pic, run it for a while, and only after  
that start it debugging (in the middle of the simulating process).

  Also some "mystic" slowdowns or speedups would really annoy me (if I  
don't have control over it).

  I don't know how the PICs works? Do they have clock/quartz input, and/or  
set up their operating frequency by them? We should do it in a way that  
resembles more the real hardware.

  The logic in/out voltage levels can be set in "configure ktechlab" ->  
"logic" window. I gues the exact voltage is known only in logic in/out.
