A script which does this:
You upload lets say 10 Files then that script auto uploads it to
Fileserve/hotfile/rapidshare ect...

Under the users login details

i.e.
i upload 5 files and within 5 - 10 minutes they are uploaded
to my fileserve/hotfile/rapidshare account's

this could be a premium service which could charge per GB or Monthly

Just an idea
