iMesh is a media and file sharing client that's available in nine languages. It uses a proprietary, centralized, P2P network (IM2Net) operating on ports 80, 443 and 1863. iMesh is owned by American company iMesh, Inc. and maintains development centers around the world. In 2009 it was the third most popular music subscription service in the US.
iMesh operates the first "RIAA-approved" P2P service, allowing users residing in the United States and Canada to download music content of choice for a monthly fee in the form of either a Premium subscription or a "ToGo" subscription. This subscription-based approach is advocated by theories such as the Open Music Model. A third option is also available for users (residing in either country) to permanently purchase tracks for 99 cents (USD) each, without a subscription.
In addition to the paid content, iMesh allows all users (regardless of origin country) access to "non-copyrighted" music and video files. A legalized ringtone download service provided by Thumbplay is also available, allowing users to purchase ringtones for their mobiles.
iMesh settled the lawsuit a little over 10 months later on July 20, 2004, where according to the RIAA, the terms of the settlement were that iMesh would pay them US$4.1 million and could continue operating as normal (unlike Grokster) whilst implementing a paid service (iMesh 6.0). iMesh had first agreed to have the new service available by the end of 2004, but this was pushed back towards the end of 2005.  due to technicalities
iMesh is now advertised as a 100% legal P2P client, and acknowledged as being so by the RIAA. This is because downloads through the client are limited to a select database of 15 million songs and videos.
The iMesh 6 client (and later versions) have achieved this by detecting attempts to download copyrighted material and blocking the transfer through the use of acoustic fingerprinting, provided by Audible Magic.
An agreement with the MPAA had also been reached. Video files more than 50 MB in size and 15 minutes in length can no longer be shared on the iMesh network, ensuring feature-length releases cannot be transferred across the network.
