Xolox kicks ***. Why? Because it can download the same file from several people simultaneously. No other gnutella client does that. The biggest problem I see with Xolox is that there does not seem to be any standard conventions for naming files. Since xolox downloads from multiple servers it must see the exact same name and filesize. This creates a problem because people tend to rename their files(to get rid of extra words like "works" or "tested") once they are downloaded therefore not allowing xolox to see that there may be many files that are exactly the same with only slight differences in the name.
