I think this is an excellent idea and will do really well. If you have developers who can walk us through real projects that can go live in the wild it will do really well. This can be like the Themeforest for screencasts. This will supplement nicely with Treehouse/Code School/Net Tuts videos because it looks like you guys will show how to do some of the rarer or less widespread tips and tricks that the big guys usually don't cover. Good luck!
