If the IFPI wanted to scare off anyone selling vouchers for the AllOfMP3.com digital download service by arresting a 25-year-old British man, and it's apparently worked.

"Until a few days ago, I had never heard of the IFPI," says one. "But yes, I am concerned about them now. Although my attorney assures me that reselling gift certificates bought from AllOfMP3.com isn't breaking any laws, it isn't worth the possibility of engagement with their legal machine."
