ClickBuster.... I am really impressed with your thinking and you sharing this!
I'll hook up a link or two to that gay domain to say thanks.. but don't hesitate to ask if you ever see anything I can do for you in the future.
have you found any limitations or problems with it since first posting this?
Do you know if it is heavy on disc or cpu load? Don't know enough to work this out myself.. but is it using any server resources during the download period or just once off when the download is executed?
