I've heard fifth-hand information (FWIW) that the PM-4, in development, is
targetted at those who have "hundreds" of ports in one location....
The PM-3 is an EXCELLENT solution. If you have more ports than that, they
"concatenate", appearing to the outside as one large PM-3 with hundreds of
ports. So I'd still say go for the PM-3 if you need to buy now.
