In the real world, I have no idea. A human looking at them could probably determine whether they're the same if they're different enough, but if they're substantially similar, then even a human wouldn't necessarily be able to determine whether they're the same or whether one is a malicious alteration. There's no automated way to decide (unless their contents are identical)."If an Atom Feed Document contains multiple entries with the same atom:id, software MUST treat them as multiple versions of the same entry"Are they still the same entry if they have different source elements that identify their source as being different feeds?
Authors of consuming applications will have to decide whether or not to obey the commandment from the spec (if adopted) to treat them as being the same, or whether to give their users the option of making that decision. Specifying that publishers who publish the same entry in multiple feeds MUST choose one to be the "original" source and express the rest as aggregated entries from that feed would make it much easier to justify treating them as different entries if they claimed to originate in different feeds.
