Ok you got me there - although I think the 'syndication' term is much more widespread ;)
But regardless, I think my point is valid. In computing names are usually chosen because they reflect something of the nature of the thing being named. The related language used around RSS is instructive - you mentioned 'feeds' yourself, for example. Names are not just abstract jumbles of letters, whatever Alice believes, but I'll avoid getting Wittgensteinian about it :P
No, although I suggested an implication rather than a legal distinction.
If you choose to publish in a format designed for portability and widely used as a syndication method, I think you'd be hard pressed to make a good complaint and feign surprise that the data provided ended up being republished by aggregators or downloaded locally by feed readers. I don't think the same applies to a webpage, or at least to nowhere near the same extent.
