BTW, a little known feature of ZIM SMS Chat is that it supports RSS!  You can subscribe to an RSS feed, and have new items posted to the feed automatically sent to your cell phone when you're not at your computer.
SMS messages are limited to 160 characters, so if the RSS item is longer than that, it gets broken up into multiple messages.  The first message includes the feed name and the item name, subsequent messages just include the feed name and a counter.  Because some people post huge weblog entries, I max out at 5 messages per RSS item.
