I got pinged quite a bit in the Q/A for my slide deck for yesterday's Introducing Features! A Deep Dive into the New "Feature" Infrastructure in WSS v3 session I did at the free virtual conference SharePoint Pro Online. I've uploaded the deck to my speaking page here: http://www.andrewconnell.com/Presentations#20071017
As for the code, it will take a few days as immediately after the Q/A, my VM bombed out on me so I need to recreate the code. Sorry guys!
Oh... the session was recorded and available for on-demand viewing... go check the conference site for more info.
Lastly, a few folks asked how I was doing those shortcuts in Visual Studio to create new GUID's and such. You can get more info about that here. And for those looking for the automated WSP creation using MSBuild in Visual Studio, a step-by-step article can be found here.
