I'd like to put some files up on my website for people to download, but since I pay for my hosting and there is limited bandwidth, I'd like to make it so that if more than X MB have been transferred, then the files cannot be downloaded again until the next month (or perhaps sync it with my billing cycle). Has anyone done this before? Is this capability already there in OpenACS? I didn't have any luck searching the forums for it. Would this be accomplished the content repository?
