emc can use a touch probe. most touch probe programs I've seen are concerned with finding Z heights at multiple X,Y locations, but there's no reason that you couldn't write a program to find points on the perimeter of an object instead.
In emc 2.2.x, the only probing move is g38.2, "straight probe". In 2.3beta1 there are additional kinds of probing moves which make it possible (in conjunction with o-words) to write sophisticated probing routines that minimize movement. Here's a screenshot showing how little wasted movement there is when probing the surface of a hemisphere: http://timeguy.com/cradek-files/emc/smartprobe.png this is using the 'smartprobe.ngc' program in 2.3beta.
