Perhaps not in large networks with very high volumes of traffic, as in 
the US. However here in Australia ISPs have successfully used them for 
Netflow based billing for years.

Can they export flows when the box is running at capacity? No, but they 
don't need to. They only need to export traffic at the peak level of the 
network they're part of. Do they have scaling issues for flow exports 
when approaching TCAM exhaustion? Absolutely.

An outright "not up to snuff for production use" isn't accurate. They 
route/switch packets/frames perfectly well.

PS-> I enjoyed your presentation last week at AusNOG, even though I 
didn't agree 100%. Sadly I didn't get the chance to introduce myself. 
Maybe next year :)
