Windows Live Writer Integration for Sitecore

Windows Live Writer is a great tool for blogging. It is simple, fast, and can be customized using plugins written in .NET. You can have web-based interface for adding your blog or articles, but integration with desktop client will not be superfluous as it provides a lot of benefits.

Integration can be divided into two parts:

1. Implementing MetaWeblog API service members 
2. Creating and configuring various handlers that will tell Live Writer how to find and use our service
