[Inkscape-user] Objects along path.

Hello,

I wonder if it is possible in any way to apply an object to a path like in Corel or Illustrator. I.e. an object which is stretched and deformed along the length of a path. I could e.g. take a triangle and applying it to a path would yield a path with a spiky tip and a blunt base, the with of the triangle. If that object was life, i.e. changing the original triangle would change the path, that'd be even more useful.

Another nice feature would be the ability to set the width of a path wither anywhere or at least at any knot -- w/o converting the path into outlines.

Cheers,

Moritz
