"Revenue Assurance" ;)

Having just looked into this recently, the options appear to be either:

1. MS-DPC + Jflow license for v5/v9 data export
2. No MS-DPC, but a different Jflow license for v10-only data export

On one side, you have an expensive card + a license.  On the other side, 
you have just an expensive license.

Of course, this is probably starting to stray a bit off-topic for 
cisco-nsp, too.  Cisco gets you, but Netflow doesn't appear to be a 
priority for their Revenue Assurance department :)
