MIAMI -- The latest effort by the record industry to stop online piracy may end up starting new file-sharing services, instead.

At first, it seemed the recording industry's threat to start suing file-swappers was slowing down traffic at KaZaa. But after an initial drop off, usage was back to normal.

Meanwhile, there are at least two services that are threatening to set up file-sharing services that can keep users from being identified.

One site, Filetopia, is already running -- and another, Blubster, is due to launch today.

A message at Filetopia reads: "What is unique to this software is the level of security and privacy that it provides. It uses a choice of strong ciphers and public key techniques for all communications and sophisticated techniques to protect your IP and thus make you truly anonymous and safe from attacks."

A similar message at Blubster also assures users of anonymity, saying, "This system allows a user's identity to remain private, which makes all the file-sharing process completely anonymous."

The Recording Industry Association of America said it will file several hundred lawsuits against individuals seeking financial damages of up to $150,000 per copyright song.
