Interested in choosing node shapes as well as colours?

Someone approached me yesterday about the opportunity to rez different shaped nodes as well as nodes in different colours. I'm slightly opposed to this, mainly because I think this introduces an extra step that most users won't want, but it is technically feasible. Is there interest in this?

BTW, if as this person did, you only want the ability to rez two different shapes you can edit the node into a new shape (I suggest you buy a new system) and use the two rezzers in parallel to each other.
