writes on his blog that
Christoph De Baene created a plug-in for Windows Live write. The plug-in can be useful for the developers amongst us (mmm are there any developers reading my blog??).

The plug-in is called syntaxColor4Writer, it enables you to embed syntax highlighting in your blog posts.

Update:  JefTek has a good list of plugins
