Whenever I think about /pop & /pvoice I imagine all the ops using the same amount of delay and even with a marginal difference in lag/whatever they all end up sending the command anyway. I think it would be usefull if you have people set with ChanServ to auto-op/voice.
If I was to get serious about having a delay I might script it so if more than one person joins during that delay time then it ends up modeing them all in one line. But even this is not all that usefull until you oping a big channel.
