Its possible???

install a PHP IRC client on a seedbox and download files from IRC channel directly to the seedbox?if yes which program suit for me?:)

thanks:)

Anything is possible, but I will be damned if I know how to do this one.

Why is this in the bittorrent section?

If its a linux seedbox, you'd be better off using a console (ncurses based) IRC client, like irssi or bitchX.

Don't know about the irc, and how you can do it, but this is a php bittorent client that you can install in an server/seedbox (http://www.torrentflux.com/)
