I thought I'd throw this very simple but highly useful tip out here because I have found that not everyone is aware of it. In fact, I was asked about this topic the other day. The question at hand: Can I create an RSS feed that opens a document in the Notes client rather than on the web? The short answer: Of course!
This is very easy to do, since you can use the Notes URI format in place of the standard HTTP URI.
Here is a snippet of XML code from a feed that demonstrates this:

Notice the <link> element references a Notes identifier rather than a URI referencing a web resource via HTTP. When users view this feed in their RSS aggregator, it will provide links that open the documents in your Notes client.
The <link> element of your feed can be constructed using a formula (usually calculated in the document or in the view column) such as:
"<link>notes:///" + @ReplaceSubstring(@ReplicaID; ":"; "") + "/AllDocuments/" +
@Text(@DocumentUniqueID) + </link>"
You can replace "AllDocuments" with the name of your view or use its design ID.
Combined with the Feeds sideshelf component in Notes 8, this makes for a very handy mechanism for distributing document updates to end users in a more modern fashion.
