Not so - I am getting netflow from VRF interfaces. What I meant was, you 
can't emit the netflow *packets* from a VRF interface.

If you're really only getting software flows, check yuo have "mls nde 
sender" configured:

FWIW, my netflow-related config:

ip flow-export destination 155.198.63.88 6999
ip flow-export source Loopback1
ip flow-export version 9
mls flow ip interface-full
mls nde sender
int VlanXX
   ip flow ingress

Netflow works with VRF interfaces.
