No imposition whatsoever.

You should check out gpasm in the gputils suite then. It supports virtually
every PIC that's out there.

Interesting combination. Why the 16C54? Microchip has a plethora of newer,
more capable, easier to use, and cheaper chips. Also because of the gputils
suite there's no worries about being able to program them.
I usually recommend the 16F88 for one off hobby designs in the 18 pin form
factor. I'm still trying to get up to speed with the 18F family, which is
far superior in design than the 16F parts. But until then the 16F877A is a
quite capable 40 pin part that can handle anything and everything you can
throw at it.

Take a look at my PIC page: http://www.finitesite.com/d3jsys which has the
designs for my trivial programmers, both low and high voltage. They will
happily program any modern flash part via the parallel port. And it only takes
a handful of easily obtainable components to put together.

Another alternative is using a chip that can be bootloaded. I'm not sure of
the status on the dspPICs from this aspect though.
