I assume that translates to "I added another NIC and switch for the internal 
networks".

More complicated, but also probably more expensive - depends what switch you 
buy (and other factors). IME, by the time you are up to the level of 
manageability that gives you VLANs on the switch, you are paying more for that 
level functionality than you'd save in the cost of the NIC.
Adds a lot of options though - I've a VM with 6 virtual NICs plus tunnel, 6in4 
tunnel, and PPPoE interfaces acting as a router at work with VLANs to get the 
networks to the right place :)
