@richwolf - Yes, you are right: the Atom feeds are part of the problem. I tried using the RSS version of the PcP feeds as well, thinking the Feed2JS-type parsers would have better luck, but still did not find a workable solution.
However, @chris, Yahoo Pipes worked beautifully! Using a mind-numbingly simple 'Fetch Feed' action it did exactly what I needed to do, and it displays beautifully embedded in the Blackboard page, whereas the other solutions like RSSinclude had all kinds of browser inconsistencies. Thanks for the suggestion.
