Thanks Aydin.

A bit of experimenting turned up how to do Cartesian offsets:
       \pnode(5,5){OA}
       \pnode([nodesep=-1.5,offset=-1]OA){OAIn}
       \pnode([nodesep=-1.5,offset=1]OA){OAOut}
More'n a bit clunky (can I define a macro that will expand
       \relpos(x,y,node)
to
       [nodesep=x,offset=y]node
so it's more readable?) but it works for me.
