Most IOS versions I've encountered in recent memory do not require a 
Netflow license.

I don't know about the CRS1, but I know on the Nexus 7000s, there is a 
separate Layer 3 license that needs to be purchased, unless you just want 
it to be a big layer 2 switch.  There might be other licenses needed as 
well.  I don't know if Netflow v9 is a separate license.  Netflow v5 
appears to be part of the of the Layer 3 license in NX-OS.
