It still doesnt make a difference....setting up routing over the PPP link
and defining the netmask of the serial line are two different things...
the bottom line is that you are using direct routes to hosts (not via a 
net) when getting from here to there on the link itself. From a 
routing perspective (where the issue is next hop), the next hop 
is the host at the end of a Point to point modeled network rather
than a gateway on a network or subnetted network. Defining it
as a network is stupid, because there is no net...there are only
2 peers.
