^^ a torrent could also help.
throw it up on tpb (ahem, MIRROBAY) or any public tracker.
filehost are useful, but subject to random changes.
at least with a torrent, it's still there (as header and data) and it's easy enough to do 1/1 p2p transfers in private, like FTP in a way.
1, create torrent with public announcements/trackers. (enable UPNP and NAT-PNP as a default)
2, send it via pm's or emails, and whoever you sent it to, is the ONLY amount of leechers you'll see...unless they themselves pass that torrent header around.
3, if '2' isn't an option, public trackers are the most likely to stay on air vs HTTP download sites.
4, thanks for the offer, bound to be many here that appreciate it.

typo.
