I don't understand the benefit of this on a router.  Except for 
connections where the router itself is an endpoint (telnet to the router, 
for example), the router has no need to even be aware of window size.

Perhaps the router's window size comes into play if the router is 
performing advanced functions such as NAT or IPSEC?
