No really new ideas, but here are some things I've known to work for others.

1. Have a really small square of binky that he can have without it being obtrusive.

2. Set limits on when or where the binky can come out. (Only in bedroom? Only on the bed? Only at nap or night? If only in the bedroom, or only in a particular chair, then he'll have to decide whether he really needs a "recharge" with the binky or whether he'd like to interact with others, play outside, etc.)

So many very "normal" people have security objects well into teen-hood. (Adults also have lots of unacknowledged totems and rituals for everyday coping!) I guess I'd deal with any ways that the binky is interfering with specific tasks or events and find a way to compromise at other times.

Otherwise, hang in there!
