ed2k links could be handled and searched by limewire, if any shareaza client has a g1 connection, so dunno why lime group is not implementing a ed2k link handling process in java and as well a ed2k hash search for gntuella,

shareaza will respond sources, which are over g1 connected and offer as well the sha1 of the file, then the download tab will search the sha1 in gntuella for the ed2k file.
