I had to dig up some old email where someone mentioned this to me.
Here's the URL:

I think AVRDUDE could also become a library, if someone wants to spend
a bit of work into it.  Most of the internal functions are already
"static", albeit a few programmers have to expose interface to other
programmers (like the stk500v2 and jtagmkII programmers share quite a
bit of code in order to implement ISP mode through the JTAG ICE mkII).
It probably requires some cleanup in main.c, and to document how to
use it.

But that needs to be discussed on the avrdude-dev mailing list rather
than here.
