As mentioned earlier, sampled NetFlow is viewed by many as quite accurate enough for accounting/billing.
If you're only looking at 1/64th of the packets, how do you accurately bill for traffic? Are you assuming that netflow would be collected on the customer-facing interfaces, and that the data for each would simply be multiplied by 64 (in the case of sampling time-based 64)?
