This means you "precalculate" the protocol and then transit it block-wise?

Yes. You just summarized in one sentence what it took me five paragraphs to explain :-)

I don't see why this can't be made compatible with the bitbang design.
Instead of the direct output the par and serbb drvier does, the pin changes
can be stored into a buffer and transmitted as a block over usb later.

Well, this sounds right. Guess I'll take the plunge and read through the avrdude code and your patch. This might be easier to do than I expected.
