i'm very happy that someone wants to work to this project...
here are some advices of mine:
1) Keep It Simple Stupid or you'll get annoyed looog before seeing any
piece of hardware/software working.
2) Do It Modular: you should be able to use the software on different
programmers. Maybe you can start with the PicStart+ which is
easyli available and works quite fine.
3) Use The Layer, Luke: Since the epoch, layer structures have been
used everywhere (think about ISO/OSI for example).
You could have a layer which flips the pins on and of but knows
nothing about the protocol, another which knows how to program a PIC
in serial mode, and another one who knows, generically, how to program
a microcontroller.
4) Write Down The Specs: Before doing everything else, the spec
must be written on paper, discussed , approved, modified, etc.
With a good bunch of specs every single programmer can
work on it's piece of code coherently with the work the others
are doing.
5) CVS: You can use sourceforge or i can provide CVS and web
space for the project.
