it would be an overall xcode/ib tutorial, that would happen to be  
showing off dk.  i think your sdk is primo for this, and it'll go a  
long ways online at the various obj-c/xcode reads/views, wherein dk  
and yourself will get some milage out of it, whilst those watching it  
will benefit/learn.  because you sdk is so extensive and for lack of a  
better word... cool, it's the perfect thing to use for a tutorial, in  
and of/for itself, and for xcode/obj-c in general.

have you setup a wiki yet?

yes, i agree 100%.

yep.  i'm telling you, you'll get a lot of play with these videos.   
your kit is the 'perfect' obj-c/xcode kit to use to learn to code os x  
style.  it has all the elements.

i trust you have a webcam of some sort?    download screenflow as well.
