UPDATE: See here (http://paulgalvin.spaces.live.com/blog/cns!1CC1EDB3DAA9B8AA!310.entry) for the latest on this project.
I created a CodePlex project today to house the Generic SPD interface code that I blogged about here (http://paulgalvin.spaces.live.com/blog/cns!1CC1EDB3DAA9B8AA!275.entry).
Have a look at here (http://www.codeplex.com/spdwfextensions) to see the CodePlex project and kick the tires.
If you’re interested in working on this with me, fire off an email at mailto:galvin.paul@gmail.com
