OK, I think I know what to do. Apparently, selecting the eraser as the default tool is already implemented in desktop-events.cpp: 617

case GDK_SOURCE_ERASER:

   toolToUse[devName] = TOOLS_ERASER;

But it's not working. I'll do some debugging and find out.

Martin, thanks for your interest. I thought I was going to be the only customer. Yes, I'm willing to implement it but can you or someone point me to which files I should look at? My experience with the Inkscape code so far has been limited to vectorizing (SSE intrinsics)  the turbulence generator and IIR filtering (I haven't checked in either, but plan to).

This is a feature I would enjoy having too. But it will require some
code to tie events and identity of the input device to the tool in use.

It shouldn't be done with the startup of inkscape, but more dynamically
with the re-selection of the right tool from the event as it happened.

Yale, are you able/interested in looking into the code and finding out
how to do the feature?
