  i would agree strongly.  putting a bunch of switches between two routers 
makes troubleshooting that much more involved.  if i can't get a packet from 
router A to router F (assuming B,C,D,and E are atm switches) where has the 
link broken down?  you have to go to each switch and look at incoming/outgoing 
cells to see which is not sending or receiving.   this scenario definately 
makes more work for the network operator doing the troubleshooting.  it 
certainly doesn't make things *easier*.
