Hey Dan, You should do a search of Wexler's site jwsound.net or the RAMPS group for your answer. Lots of pros there. Although this doesn't answer your question directly, my approach is to use a lockit box on the camera that is jammed to my 744T.
Try sending it to a wireless xmitter and linking to a receiver at the 744T. You don't need to pull the level down to keep out of the way of an adjacent audio track, but I'd try the feed at maybe -10dB.
The real question is, why bother? Why not send reference audio to the camera and use Pluraleyes to sync the two in post?
