Creating Marketing web sites with Flex and Flash

This is the question that have bothered me for the past 6 months ever since we have successfully created and launched the first Flex application in Gugga, the Content Management System for the new Dewars Platform and seeing how powerful Flex is.
Is it crazy to think that Flex can be used for creating highly engaging and interactive marketing web sites. On one side Flex has been marketed as Rich Internet Application technology on the other every time someone mentions engaging animations and custom interactions everyone from Adobe backs off and says Flex is not about that.
Adobe also introduced a very important concept,use Flex as the application engine and plug custom components into it made in Flash CS3.
We are in the process of migrating the Gugga Flash Framework to Actions Script 3 and we are going to experiment with this approach. Let's all hope it will turn to be a win win situation by using the best of both worlds Flex and Flash. If the result is what we expect it to be it could turn the tide and change the whole process and way of thinking about approaching such projects
