A few months ago I found this interesting suggestion
http://radio.userland.com/stories/storyReader$19964 .

I tested it on a few aggregators but no one supported it.
Only NetNewsWire seems to do it, according with what Dave wrote.

I think this is a wonderful feature if you can't setup an HTTP 301
server side redirect.
Actually many users write a one-item feed telling subscribers the feed
moved to an other location.

What do you think?
