Hi Bert,
First of all...Great idea :)
Now, we could work together on this, but I've already gone in a different direction from you, I won't be creating a starter kit (at least not in the first idea, later on, maybe to demonstrate some kind of sample code guidance), but rather a set of real Visual Studio templates with wizards and such.
Also as for MSBuild, I've already made a small MSBuild WDP which deploys the dlls to the main dnn, and it is totally generic, in your approach you hard code the paths to dnn and such. I will continue working on the MSBuild file until I cover most of the basic deployment scenarios (next thing is zipping and packaging, hopefully I can continue on the generic, no hard code streak)
Later on I plan to develop a CI strategy, module testing harness, and everything else, by that time also Philip Beadle will join me on the project as he has contacted me with this desire.
So, if you see yourself in this team also (which would be great, only with the integrated work of all of us we can make this into complete guidance package), and want to help with the whole thing, contact me by mail and in a week or two when I finish the bits I'm working on (to finish what I started) I can see which part of the idea you can handle and we can "mingle".
how does that sound?
