Link-local v6 and mobile phones

Hello, a little question :) For mobile operators using v6 on their networks, how do you manage link-local communication between mobile phones ? While I understand it's layer 2 related, am i able for example to make ping sweep and be able to communicate directly with other phone (customer) ? -- Willy Manga (from where I stand mobile operators do not use yet v6 :-\ ) freenode: ongolaBoy Ubuntu Cameroonian Loco Team https://launchpad.net/~manga-willy
