You can click on the box next to a user you don't want to see. IGMPv3 will have the ability to specify the sources you want (and the tools will presumably be upgraded to use that interface) so that when you click on a box a prune can get sent. mrouted version 4 will have source-specific prunes to be able to assist this functionality, meaning that the "offender"'s traffic will not even get to you. Given that the MBone tools implement the lightweight open sessions that they do, there are severe security implications for allowing some arbitrary person to prune off a source. Bill
