A friend of mine is about to launch his new software product called ViaList. ViaList allows you to simply create all types of lists; to-do lists, shopping lists, or just personal reminders. Then these lists can be shared and/or displayed on a web page. And the web pages are RSS enabled allowing for sharing via various feed readers.
Please vist ViaList at http://www.vialist.com. Currenly, the client software is Windows only (sorry OS X users).
