Service been in beta mode in U.S. since Oct.

iMesh has expanded its label-authorized peer-to-peer digital music download and subscription service into Canada.

The service, powered in part by MusicNet and using audio fingerprinting and filtering technology from Audible Magic, has been in a public beta test mode in the U.S. since October. No word yet on when either the U.S. or Canadian services will emerge from the beta test version.
