Ok. A fast note on XML-RPC just in case I ever need a server implementation of this kind, this application tracks changes to news-oriented websites. Should be useful when developing a blog’s directory or a pinging service.

XML-RPC it’s a spec and a set of implementations that allow software running on disparate operating systems, running in different environments to make procedure calls over the Internet.

It’s remote procedure calling using HTTP as the transport and XML as the encoding. XML-RPC is designed to be as simple as possible, while allowing complex data structures to be transmitted, processed and returned.

Also note that there are 2 methods: weblogUpdates.ping and weblogUpdates.extendedPing
