Shouldn't NAT state (on Cisco routers) be shared among all interfaces
configured as "ip nat outside", so that load sharing doesn't interfere
with NAT state?  (As long as no fancy route-map NAT configurations
with interface dependencies interfere, of course)

Of course it will not work if those T1s are terminated on different 
customer-side routers.
