Paul, there might be other solutions as well, but there is an internal function in the igraph package that can draw curved arrows, it is called igraph:::igraph.Arrows(). As it is an internal function, it is not documented, but I think it is pretty straightforward to use. For the 'curved' argument you can give a number, try values between 0 and 1, or (if I remember well) -1 and 0 if you want it to curve towards the opposite side.
