Who calls here with a gutshot?

Normally this would be a fold for me, but I wonder now if implied odds justify it..

Flop: (5 SB) A[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/heart.gif[/img], 6[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(5 players)</font>
SB checks, Hero checks, MP3 checks, CO checks, <font color="#CC3333">Button bets</font>, SB calls, Hero ???

I am in position to trap at least one player for an additional bet on the turn, in addition to whoever after me might call 2 cold (I'm not counting on it). Only thing I'm worry about is the bettor has nothing and checks the turn.
