I just posted a non-Flex multicore example. Take a look.http://www.as3dp.com/2009/07/22/a-non-flex-actionscript-example-of-a-puremvc-multicore-application/
Describes the design and development of a simple game concept to exemplify the utility of PureMVC multicore. This is a pure AS3 app that doesn’t use the Flex framework. You can download the source and build the app in Flex/Flash Builder (as an AS3 project) or Flash CS3/4.
