LimeWire Regains Top Position

LimeWire has been noticeably quiet on the public relations front. This is understandable, as LimeWire was the recipient of an RIAA cease and desist letter in September of 2005.

"We demand that you immediately cease-and-desist from enabling and inducing the infringement of RIAA member sound recordings,” the September letter said. “If you wish to discuss pre-litigation resolution of these claims against you, please contact us immediately."

LimeWire was not the only recipient honored with this letter. Several other popular commercial developers had some difficult decisions to make as well. WinMX and BearShare folded like cheap suitcases, while MetaMachine (eDonkey) “threw in the towel.” Ares Galaxy, considered by many as a heroic network despite the occasional spotty performance, released its source code. LimeWire, the leading Gnutella client, hung tough however and has to some extent remained in favor with the music industry. It has made efforts to develop an unauthorized content filtering system, along with a popup screen warning users against infringing use.

LimeWire has also remained in favor with the P2P community. Collaborative efforts with its alter-ego FrostWire have allowed a wide margin of forgiveness for any perceived cooperation with the music industry, while continued development improves the quality of the Gnutella network. In addition, its freedom from any type of third party software (i.e. spyware, adware) has returned LimeWire to an old honor.

Once again, LimeWire is once again the most downloaded-per-week application on After nearly 3 years and 86 million downloads, LimeWire has managed to edge out other worldly applications such as AdAware, Spyware Doctor, Morpheus and BitComet. Last week, LimeWire managed 926,598 download. The next file-sharing client, Morpheus (which ranked 5th) scored 380,872 downloads.

Development of the LimeWire client is also gearing up for its next iteration. On the LimeWire blog, which announced the arrival of version 4.12, the development team touched on the upcoming BitTorrent and “custom” DHT (Distributed Hash Table) integration.

The announcement of the two features simultaneously is considered by LimeWire to be “coincidental.” The custom and open source DHT will be specific to LimeWire and the Gnutella network, and will function to enhance the indexing ability and cohesiveness of the network, along with “adding more security features, better spoofing-checks, etc.” It will have no interoperability with the Mainline or Azureus DHT network.

"First, it's important to understand that the DHT and BitTorrent are being developed as two separate features," LimeWire developer Mark Kornfilt told "In the future, one of the uses of our DHT will very likely be to support trackerless torrents, but we are not developing it for this sole purpose.

"Over the last few months, we have developed the Mojito DHT, which is our own flavor of a Kademlia DHT. It is going to be used as an additional structured overlay on top of Gnutella. What this means is that we are going to have a hybrid system, where the unstructured network will be used to bootstrap and perform initial maintenance on the structured network, and where the structured network will be used by Gnutella peers as a query structure. Both network will therefore be independent (after initial bootstrap), but will be used simultaneously to get the best outof both worlds."

LimeWire developers also hope their Mojito DHT layer will be utilized independently by alternative developers and networks. Staying true to LimeWire tradition, Mojito DHT will be open source, allowing for developers to improve and implement the technology as they see fit.

"I'd also like to add that we are putting our best efforts to come up with an efficient, independent and clean DHT API (the Mojito DHT) that developers can easily use. To our knowledge, that doesn't exist yet in the Java world, even though I believe that structured networks are going to become more and more used over time.

"We are currently in the process of writing a specification for the hybrid system, which I hope will help open-source developers understand and contribute to our project."

Unlike the remnants of the old P2P guard, LimeWire is determined to innovate Gnutella technology. The integration of Mojito DHT is a significant step forward, and will help bring Gnutella towards the forefront of P2P progress.
