i'd suggest to password protect the file instead of the hosting site.

instead of relying to 1 hosting site, try mass mirror hosting sites (aka 1 upload, multi download sites).

http://www.uploadground.com

http://www.rapidspread.com

http://www.sharebee.com/


Single hosting sites:

http://www.sendspace.com/


the suggested sites are recommend because of its clean interface, no/almost none advertisements, etc.

last time, i used other hosting site with lots of p*rn advertisements. when i gave the link to my director at overseas, he told me he's almost blind with all those flashy ads! luckily he didn't mind.
