Some romhacks are too big to host on RHDN, and this may lead to them being lost. I can understand bandwidth costs make it not viable to host them directly on the site. Websites and cloud storage inevitably die. So I propose this solution.
1. A torrent is produced which collects all of these romhacks in one package. This would greatly increase the chances of them being preserved.
2. These romhacks are preserved on RHDN servers as a backup, but aren't made available to download. This is just another layer of backup.
3. RHDN has offline archives of all the romhacks on the site, including the ones too large to host. At least several copies are made and periodically updated.
