Given that it is currently ultra-simple I'm happy to bump it up to plain 'simple' with the addition of an optional attribute. Philipp is right about not sending probes being problematic... other IM networks do not show all contacts offline when you are invisible, it's quite user-unfriendly to do that. Still, it does have privacy issues - and thus I'm happy to push the choice to client developers (they can either make the choice for their users, or push the choice to users through a one-time prompt or such). I don't think this is the kind of choice that should be made by protocol designers, sometimes users are willing to risk theoretical presence leaks just to avoid their boss seeing them online on a Saturday :) Regards, Matthew
