NFA 6.0 and Riverbed Steelhead WAN Optimization Appliance

We have WAN optimization appliances called Riverbed Steelhead among our Data Center and 2 of our biggest remote sites.

NFA are getting Netflow data from our Cisco Routers but the problem is the bulk of the traffic being seen are those optimized data to and from the Riverbed appliances.

In the top Application Report, NFA just sees them as TCP_App.

We found out that you can enable Netflow on the Riverbed Appliance.

Do you support Netflow traffic coming from Riverbed Steelhead appliance?
If yes, how do you configure the NFA and Riverbed to talk?
Can NFA accept Netflow from both Cisco devices and Riverbed at the same time?

Thanks...
