OK.  Well, most TPI chips are quite small anyway, so that's certainly tolerable.

My only concern with these patches is the D2XX driver. First, it is only 
available for some of  the OSes AVRDUDE runs on.

More importantly, it is closed-source (correct me if I'm wrong), so we are not 
allowed to include it as long as the project is hosted at the FSF. I'm not sure 
about the source code itself, but at the very least, I could not provide 
Windows binaries that require the user to install closed-source software first. 
(Is linking GPL'ed software against such a library legal at all?, assuming the 
binary is to be redistributed.)

An I correct the TPI patches itself will also workk without D2XX?
