LocalNames is about having short names for things. For example if you type sd it would make that http://slashdot.org. This is very similar to things like abbreviations in jEdit, except thats it meant to be used with everything from wikis, blogs, email, what ever. The server speaks XML-RPC so anything could talk to it. I would be cool to see a JEdit plugin use it, although i know 0 about programing in java. But I bet I could write some perl, that could utilize the list and add it to my JEdit abbreviations list since thats where I spend most of my time these days. Looking at some of the documentation there seems to be someone working on a wordpress plugin for it. Cool stuff.
