It's new in 12.3(14)T so is in 12.4(1).

"The NAT Virtual Interface feature allows all NAT traffic flows on the virtual 
interface, eliminating the need to specify inside and outside domains. When a 
domain is specified, the translation rules are applied either before or after 
route decisions depending on the traffic flow from inside to outside or 
outside to inside. The translation rules are applied only after the route 
decision for an NVI."

I couldn't get it to work on a 1721...

May have been just user error though, so I haven't logged a CCO case about it 
yet.  Need more time to fiddle with it first ;)
