I’m developing a project this year around the RSS Cloud protocol.
As a starting point, I’ve written a a short and sweet WLW plugin.
I’ve got it installed locally (eating my own dogfood), mainly cause useful in testing my system once its written.
This may be a bit of a contradiction in terms since wordpress.com already supports RSSCloud (you’ll see a RSSCloud tag in my feed if you view source. It gives the details of the wordpress.com aggregator).
By default it will use Dave Winer’s test server as an endpoint so make sure you change your settings before use.
Its available at codeplex here: http://rsscloudnotify.codeplex.com/
The source is in the repository if anyone wants to look at it. Its not quite ready for prime time yet. 🙂
