an initial version of a simple UV copy script, gotta decide and implement the UI integration still, is .. eh suboptimal here, but is noted with XXX in comments with suggestions :) .. thanks for theeth and others on Elysiun who made this, and for Unnamed on irc for digging up .. seems that NMesh -> Mesh conversion was not necessary, but might be a nice excercise.
