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.
Best,
Gabor
