That's quite hard to do with persp because it needs to plot the segments 
in a certain order.  You can do it in the rgl package using persp3d for 
the first surface, then persp3d( ..., add=TRUE) for the second.   Note 
that persp3d and persp use slightly different conventions for how to 
specify colours; see ?persp3d for details.
