You are screaming Wloader's name:

- Downloads using a serial bit interface on the single port pin of your choice.
- Automagically moves locations 0-3.
- With an offboard dongle, the programming circuit only adds 2 pullup
  resistors to the target (MCLR and the serial interface pin)
- The complete dongle with automatic reset uses 4 resistors, 2 diodes, and
  a transistor.
- Serial interface specification completely documented.

You can find wloader here: http://www.xs4all.nl/~wf/wouter/pic/wloader

My discussion of wloader and the Linux based tools I use to use it can be
found on my PIC page: http://www.finitesite.com/d3jsys/index.html

Hope this helps,
