Member download limit

[Bhunter]

I would like to implement such system to my site where trail members will have a daily download limit.
I'm using ccbill as my e-ticked profider.

How can I setup a system like this?

please anyone can give some input?

if youre using authentication through the .htaccess file it would probably better to make separate folder with a little piece of downloadable content just for the trialers. if not (php+mysql and sessid or whatever authentication) you could assign a particular variable (meaning volume) to each piece of content and just control the overall volume through the sum of these variables in a DB

Thank you for your reply.
Is there a perticulair script for this? sessid?

What i want is to give trailers a pass to the whole members area, but with a limited daily bandwidth use.
