Some have default ports, but they are widely ignored because historically ISPs used those ports for throttling. > When people ask my advice about computers, I always include: "Never > use Limewire, or anything like it." They are as dangerous as you want to make them, I've been using bittorrent and eD2k for years and have never seem a single virus, trojan etc. I've seen a few on USENET but they've always been laughably obvious. People that end-up with that kind of thing are normally actively seeking executables. If anyone wants to discuss p2p blocking I'd suggest you start a new thread.
