Keep your enclosures off my aggregator. Or something like that.
A feature request for anyone doing an RSS aggregator. Watch for enclosures. When you spot one, make note. If you're running at 2AM (a configurable time) download all the enclosures you've found, and put them in a folder on the local hard disk. Present them to the user when he or she arrives in the morning. This way large media objects, songs and movies, can be transmitted overnight using the network defined by RSS. This idea came from Adam Curry.
Actually, please don't. If I want "large media objects" I'll go get them by clicking on a link. I'm happy to use the network defined by TCP/IP, and I'm willing to download things in the background in real time. That way I, the user, stay in control, and RSS doesn't get used for multimedia spamming. Thanks for listening.
