The sheer volume suggests that these cases aren't designed for prosecution—and they don't need to be. As the RIAA lawsuits showed us, most people will settle. Data from the recording industry lawsuits, revealed in a court case, showed that 11,000 of the 18,000 Does settled immediately or had their cases dropped by the labels. Seven thousand either refused to settle or never responded to the settlement letter, but after the RIAA subpoenaed their identities and filed "named" lawsuits against them, nearly every one settled.

After years of litigation, the number of people who have pursued a trial all the way to a verdict can be counted on one hand.

The legal campaign has the potential to earn real money. Copies of the settlement letters and settlement contracts seen by Ars Technica show that Dunlap, Grubb, & Weaver generally asks for $1,500 to $2,500, threatening to sue for $150,000 if no settlement payment is forthcoming. Assuming that 90 percent of the current targets settle for $1,500, this means that the lawyers, studios, and P2P detection company would split $19.7 million.

Once the infrastructure has been set up, this sort of system is simple to replicate, since it's built largely on sending out letters and collecting cash. If the lawyers can continue signing up indie film clients at the current rate, they could be on their way to filing nearly 30,000 lawsuits by year's end, which would double the potential cash on the table.

Time to repeal copyright law.
