custom HPTuner/LS1Edit/... cables?
Doing a little investigation now, for a potentialy great project. Will be an open source tool for fellow LS1rs

You need a Motorola (FreeScale) MC68HC58 Data Link Controller to interface with the OBDII/VPW port. You would also need to implement a PIC chip or some sort of buffering interface to support block mode if you are going to do calibration/OS uploads/downloads.
That is the easy part really. The next part is writing your own boot loader and figuring out how the Seed Keys work with the different VCM's.
I can give you more info but it will need to be offline as I am not sure discussing this here is allowed.
