Our local Juniper partner claims that a special Multiservices DPC card is needed for netflow v9. DPCE 4x 10GE R can run tunnels like GRE, IP-in-IP but not netflow services:-(. I can't understand why such a complex card is needed for netflow v9 functionality and I'll be glad to get some feedback from the list about the issue. Are there any plans to port netflow v9 functionality to 10GE DPCs?

This is correct. To do v9 is far more processor intensive, hence you 
really don't want to be doing this on the Routing Engine, as is the case 
with v5. All this functionality is off loaded onto the MS-DPC instead.
