upload to file sharing service / link as attachment

hi all,

my host has limited uploads via php to 12MB which makes things very annoying! I cannot find a way to add attachments that are larger than this to articles in drupal. Is there a module that will upload to something like mediafire or rapidshare via drupal and add it as an attachment? this would be great as it would save bandwidth and could be linked to an account so files end up in the same place.

i've seen the video upload module does a similar thing for video using youtube.

if anyone can help please let me know! even if i could upload it somewhere other than my site and add a link as an attachment would be better than nothing.

(btw i've tried changing upload limits in .htaccess and php.ini etc. the host has forced it to 12MB)
