Ah, yes. I like it, Owen. Neat, given the contraints of the tool.
I guess the only question I have is how you decided what to assign the
results of the loop to. You used item.loop:yql. What does the colon
mean? It seems to imply there's a hierarchy in the data, which I
guess is right. And what would have happened if more than one row had
been returned from the YQL?
Anyway, thanks again.

As you noted, there isn't really a good way of doing a 'join' in Pipes. My approach uses a combination of a Pipes loop and a YQL query which extracts only the data you really want from the second dataset. I haven't got time for more detailed documentation at the moment I'm afraid, but feel free to have a look at the pipe source if you are interested and I'll answer questions if I can.
