Yeah, I'm curious to hear what the OP thinks a disassembler is useful for.
I've been doing embedded firmware since before many people on this list were
born, and I don't remember a case where a formal disassembler would have
been useful.  I know reverse engineering does occur, but it is a tiny tiny
fraction of overall engineering.  If you're trying to replicate a PIC
system, it would usually be better to start with the specs and create your
own firmware than to try to disassemble someone else's code, especially
since most code out there is crap to begin with.

I do implicitly use the disassembler built into MPLAB during debugging, but
that is just to get a instruction level view of the immediate code around
what I'm debugging.  For that purpose, the MPLAB program memory window in
symbolic mode is fine.  I've never wished for something that could take a
whole HEX file and turn it into assembler source.

It's a big world, so somebody out there may have this need.  However, trying
to make money off a PIC disassembler sounds like a losing business
proposition.  A few people might try it as a curiosity if it were free, but
very very few (probably none) are going to spend money on a disassembler.
