There goes my favourite transfer proto :) fortunately, Tony doesn't get to decide what is broken. by now it's pretty obvious to almost everyone that SL is unworkable, and that deprecating them is the Right Thing. so apps won't have to deal with SLs. this is the best thing that could happen to IPv6.
