The Really Simple Discovery specification makes it very easy for xmlrpc client to discover the xmlrpc url as well as the xmlrpc APIs that blogging software supports. If this is implemented, all a user needs to know is the blog url, and their user name and password. They will not need to know what url needs to be used when using xmlrpc communication.
I decided to implement this as a plugin for LifeType 1.2, and it works very well. Here is the wiki page for the plugin. I will update the page to include the real link, once the 1.2 plugins are pushed to sourceforge. In the mean time, the plugin can be downloaded though svn or in the latest snapshot.
