XoloX, getting off topic a little. These are interesting links: 1. Main site & versions, 2. Gnutella timeline,
3. Gnutella history wiki, 4. XoloX wiki

XoloX was closed source. Last link was interesting. I see it's development closed down as did the XoloX section on these forums.

BTW downlding from Shareaza (RAZA) users (most people know what I mean ... generally 0.1 -> 2 KB/s for large files) is a typical example of why having multi-net clients doesn't work very well. One or more of the nets get sacrificed. If they only connected to one at a time, then fine.
