Kosher shavers

This past week's Mishpacha newspaper had an article which stated that a group of Rabbanim in EY, with the approval of R' Elyashiv, have started talking to a major European shaver manufacturer (I assume Phillips) about building "kosher shavers". They will build a shaver that is kosher לכל הדעות. The big question will be how well could such a shaver work?
