This is sometimes possible, but not always. Here are a few cases I can 
think of where it isn't:

* If you've got IPMI piggy-backing on a physical interface, you may not 
want it to be on an Internet-facing LAN.
* If you have a particularly fast ethernet device you need for a storage 
network.
* If you've got a subnet that needs to use jumbo frames but only one NIC 
supports frames large enough for your application...
