If I'm understanding you, I think you could do what you want using threads posted in forums without any changes. You'd just have to use the feed manager to set up a different feed for each forum (I'm assuming the yahoo pipes thing lets you construct a feed url that provides the articles filtered in some way).

As for making them articles, I have to admit I'm not as familiar with the CMS as I probably should be, but I think articles are nasically threads, so that it might only take relatively minor changes to the rss poster code to make articles instead of threads.
