This is quorum agreement that a task is done.

Think of providing an interface for a one-shot distributed recursive query. When should the consumer be given "the answer" for some definition thereof?

[palvaro]

don't we already have this module and isn't it called "voting"?

[jhellerstein]

I think it'd use voting and maybe some reliable delivery protocol (perhaps one based on counting). The thing that needs to be voted on is something about acks of dataflow messages.
