PIX and Nat'ing the outside world.

Hi,

I understand nat going outbound is to hide the inside network.  Would there be any reasons to nat the outside network on the inside interface?

Yes, if you have overlapping addresses, or routing issues to specific subnets.

An example given in Cisco docs is a DNS server on the outside with an IP address that conflicts with perhaps one of your own subnets. You can nat that to appear to your inside hosts as being local.
