Students sued by the recording industry for using the now-defunct i2hub online file-sharing network are demanding that the network’s operator pay to settle music copyright-infringement claims.

Attorneys with the Student Legal Services Office, a student-funded legal group, claimed i2hub placed ads on the University of Massachusetts-Amherst’s campus to deceive students into believing the software was approved by the university.

At least 42 students have been named as defendants. The recording industry trade group has offered to settle each case for $3,750, lawyers for the students said.

Wayne Chang started i2hub in 2003 while he was a student at UMass. The network linked people at hundreds of universities over the super-fast Internet2 network. Chang shut down i2hub in November under pressure from the recording industry.

Chang’s attorney, Charles Baker, says his client is not liable.
