I use TwoBoxToolKit and it works pretty well for accepting escort quests. My clones are set to "Auto Accept Quest" so as soon as my main takes the quest, I see the text "Escort Quest Accepted" pop up in my relay channel. It's a huge convenience for doing the Skettis escort quest, especially on a pvp server. So I can just fly in, talk to him, and have all my characters on the quest and ready to go.
