I am checking out Corona SDK and looking to adapt the Coffee Demo ( http://blog.anscamobile.com/2010/09/create-scrolling-list-views-with-text-and-graphics-in-coronasdk-ios-android-tutorial/ ) so that it uses the Retina Display @2x image configuration described here: http://blog.anscamobile.com/2011/01/dynamic-image-resolution-made-easy/
What would I need to do to integrate the Retina 4 stuff into the tableView library and thus make the Coffee Demo auto Retina 4 image compatible?
This is actually an "Interface Widget" available in Corona that produces tableViews that are compatible with retina displays:

And more Corona SDK user interface widgets here: http://developer.anscamobile.com/content/widget
the answer is on the second link you provided... I quote:
As noted above, dynamic image resolution works in conjunction with dynamic content scaling (documented in the “Configuring Projects” section of the documentation). For further reference, the dynamic image resolution docs arehere.
To use this feature, you basically need to do two things:
- Use display.newImageRect() rather than display.newImage() when loading your images
- Specify one or more scaling thresholds in your project’s config.lua file The syntax is as follows:
display.newImageRect( [parentGroup,] filename [, baseDirectory] imageWidth, imageHeight )
imageWidth is the base image’s width in the base dimensions of the content.
imageHeight is the base image’s height in the base dimensions of the content.
- parentGroup and baseDirectory are optional, and can be omitted; they behave in the same way as their counterparts in display.newImage().
