Sudheer Satyanarayana has this new post on his blog today talking about a simple way (via a PEAR package) to make an XML-RPC connection to ping technorati about updates to your blog.

In a previous blog post we discussed how to consume the Technorati ping web service using XML-RPC. The PEAR package XML_RPC2 provides convenient client and server objects. You can call the remote methods as if they were the methods of the client object. In this post, let us accomplish the same using a PEAR package XML_RPC2. We will write a client script to update Technorati when there is new post in your blog site.

You'll need to grab the XML_RPC2 PEAR package to make this all work, but once that's installed, you're a quick few lines of code away from a client to update Technorati with the ping information for your site.
