Do-able, though I'd actually have to open a {Gasp!} Manual or Datasheet
to do that - you really expect me to be able to do that?  <G>  I could
see having a "control panel" type applet in there that does the advanced
options, and have the usual interface be VERY much simplified;  Let's be
honest, though, by the time someone's taken the time to learn assembly
for the PIC series, they probably CAN cope with the current MPLab
interface (I deal with Needham's EMP-10, EMP-20, MLab, the gang
programmer, the Parallax interface, the Atmel interface, and about 8
other IDE's some months, it's not THAT bad - after the first time, you
usually have it fairly well figured out.)

Trust the user, though <G>

I've thought of a "Laptop-based" mobile development system, for in the
field - battery powered, able to supply power to an attached DataRase ][
on a timed basis, maybe some day I'll get moved in & do it.  Don't hold
your breath, tho <G>  If Canon can put a printer in a laptop, I can put
this in one <G>
