Information logged by the Concurrency Server can target accounts ripe for upgrade. Residential users may not realize that they're stealing service when double dipping, and may pay incremental fees for this privilege. Connection records can be logged to a file, but anyone relying on this for billing will use an SQL database. Funk argues that ISPs under-estimate both the extent and cost of concurrency abuse. They say that early adopters are reporting abuse rates that double pre-deployment estimates.
Abuse increases operational cost by inflating port, server, and bandwidth utilization.
By reporting usage accurately, ISPs can eliminate lost revenue, convert some portion of abuse into new revenue, and boost their business valuation. Funk published an analysis demonstrating potential incremental profits. But Funk's estimates are not outlandish. In fact, they're pretty conservative. In this example, the Concurrency Server pays for itself in two or three months.
