File Download Manager

We have an asp.net (vb.net) website under development that needs a download manager component. The primary purpose of the site will be to offer file downloads to users. For those users with a 'free' account they will be sent to a website within IIS that can only process so many simultaneous downloads at once. Paid members will access a site that has no limits other than a bandwidth throttle that we will set in IIS. For the solution that is developed it should have the following options:

1. Be able to configure or not configure for seperate IIS sites on the same server.

2. Have a way to set the max download count coming from the server. Preferably in a web.config.

3. If the max download count is reached a user is given a 'download ticket' and when a slot becomes available they are allowed to download the file. Basically if there are no open slots they wait in a queue untill one is available.

4. Have some sort of feedback for the user, such as 'you are #5 in line', or you have approx 10 minutes untill your download starts.

5. (Changed on 11/8/1005) Originally we required this to be developed in vb.net, now we are opening this up to other languages. The functionality can be developed in any language as long as it meets the following requirements. It must work within an Asp.net web page, and second, it must not require any user installation to work, no browser plugins, etc. It must all be server side and/or use client side scripting.

A good example of this technology is in use by rapidshare.de. We encourage any bidders to check that site out first to get hands on experience for what we want. NOTE: Please include a description of how you plan on developing the solution.
