Ability to Restrict amount of downloads from Attachments

[shiva]

I requested this before, but no one came up with a solution, so I am doing it again here.

I need the ability to restrict the amount of attachments for certain membergroups. The strain on my server because people are greedy is causing a lot of problems.

Either by a amount of attachments a member can download per day (like say just 5) or even the ability to have a page that comes up with a countdown of a time period, before the link will appear to be downloaded (Should not be a pop up page, just changes the page from the thread)

Please, I have no idea on scripting, and this has killed my server a few times, and one of these days, I may go over my bandwidth limit.

Help?
