I agree wholeheartedly, although 1.2TB is extremely large. My interest is mostly music though.

You should link to some good clients on that page, because like you said Limewire is widely used, which I take as implying other BitTorrents clients aren't. I would recommend Azureus, uTorrent and as long as it's legal the official BitTorrent client.

Unfortunately music on P2P while commonplace is not legal in the US but everywhere else its tolerated to one degree or another.

Because the tablebases are so large, P2P is useful as the FTP error correction capability is weak when dealing with large files.

The problem is because of abuses, some P2P software vendors have been sued to death. Others like Limewire are under constant fire but remain quasi legal because of the disclamers.

Legit uses exist, the computer chess is one example. The problem is that everyone shares music, and no wonder the RIAA is suing. On my system, only tablebases, al 7.05GB of them are shared.

Still looking for a magnet creation tool, to suplement the torrent by offering a choice to users who want to download free tablebases to enhance their chess game.

Chess is extremely popular in Europe, where it is played widely and where 3/4 chess engines come from.
