Idea
I've found a software niche that's not being filled: RSS reader for PalmOS. There's BlogPluck, but it requires Plucker, which I wasn't particularly thrilled with when I tried it. Perhaps it has gotten better, but I still think a standalone RSS reader would be worth creating.
I'm playing with the idea of writing this myself. The Palm side of it should be real easy -- I'm just displaying entries from a Palm database, and possibly a configuration menu. The conduit will be the most work, but once you have the RSS parser, the rest should be fairly simple.
Just an idea. If I can find time to work on it, I think it will be a worthwhile project.
