Unconfirmed media reports here say that four major Japanese Internet service provider organizations have agreed to sever the connections of users who habitually use file-sharing programs such as the homegrown "Winny" program.

According to the reports, the ISP groups believe it is possible, with the cooperation of relevant right-holder groups, to identify such users and cut them off from Internet access. The ISP bodies and rights-holders will reportedly meet in April to draw up guidelines spelling out grounds for such action.

Attempts to obtain confirmation of the move from the ISP groups and rights-holder organizations such as the Recording Industry Assn. of Japan and local authors society JASRAC were unsuccessful at press time.
