Well it seems to be a wonderful combination: Create content in WordPress and reuse the content inside a nice Flash-Frontend with swfobject detection. Obviously we will have a couple of advantages resulting out of this:
1. Full XHTML Support as a fallback.
2. Full featured Flash page with content management
3. Rights management for the content management
4. Maybe even WYSIWYG content editing through a flash Rich Text Editor.
Sadly, before we can profit from all of this, there are a couple of changes to be made inside the wordpress core. XML-RPC works pretty well to read posts in categories and post into categories. What if we want to have a structure made of pages and subpages?
My approach to combine all of this and get over the little problems, i have set up the following structure:
1. Installed WordPress 2.1
2. Installed a really minimalistic Theme (we can change that later).
3. Inside the theme we have swfobjects implemented to exchange the whole content and navigation section with a swf object.
4. The Flash frontend for the content and the Flash frontend for editing content ( both based on mattismes xml-rpc classes).
The actual state of development can be checked here.
