Now now, me may have it all wrong. Perhaps this is for completely legal reasons.
His friend probably wants to send him 1 GB of wedding photos/videos from the summer. Being as large as they are, email and IM file transfers are out of the question.
He downloaded the torrent from his friend and is now wondering what the next step is...
I know I've been there. Created a torrent for a friend and FAILED horribly... then I just ran a temporary FTP server and told them to get it over night. (FTP Resumes, yay!)
