That's an excellent idea. Since I had something like Pajarico's other
suggestion in mind (see different email), I was thinking about how to
store per-node information. But separating the width info from nodes and
storing it in the described way will make the LPE very powerful and
flexible.
Its an excellent idea until you make any change that substantially alters the path length, at which point all your widths 'slide' along the path when you didnt want them to...

I'm not sure if I understand you correctly here (in particular: what do
you mean by "profile shape"?), but why not apply the LPE to any path
whatsoever? The 2geom routines are flexible enough to make this
possible. If you want it to be on top of a spiro path, just use LPE
stacking.
