As described in this blog post with accompanying video, it’s now very easy to embed the output of Yahoo Pipes into, well, anywhere.

For example, I created a Plazes Feed Mashup Pipe that takes the XML of my most recent 100 Plazes presences, massages the XML into something resembling RSS, and then outputs the result on a Yahoo Map.

(There used to be a Yahoo-Pipres-generated map here; but then Pipes went away. Leaving the post here for posterity).
