That'll probably depend on the individual filehost. Best check on the terms and conditions of the ones he listed, but they can always get taken down pretty quickly, but it shouldn't be a problem if you're not spreading the link around. I'm sure you'll have more than enough time to download the files though.

Sounds very cheap for the service you provide and especially for such a large filesize, but can't people get banned from private trackers if they let others download their torrent files, or does it have to be a non-private tracker?
