if you get sued just because of the torrent thing, Microsoft, IBM, Bungie(our good old Halo) and other big companies will be too, because they use that protocol to spread their softwares... most of the online gaming you play with actually are using similar torrent protocol to exchange files...

the only point with torrent and legal threat is the same with any other software where you can download something... ftp, afp, etc... all files protocol have pirates on 'em...

torrent is great to share films between users... a clan of gamers can share the same films of their games when they have them on a torrent tracker per example... it's bigger for a server to host ftps...
