Frog CMS

Question:
Wat is the best way to connect a Flash (AS 3.0) Frontend to a Frog CMS backend?
I am using SwfObject, and want to use SwfAddress (for deep-links => seo-optimalisation) also.

Description of flash site:
Has about 5 pages and on 2 pages there is a submenu.

Possible methodes?
1) Use AMFPHP to get everything out of the database on-the-fly and with the fastest datatransfer
2) Use PHP + jquery (or Prototype) to get everything out of the database when loading the site (so that you don’t need to load anything later on in the site)
3) Use jquery (or Prototype) to load only the text of the page where your on (and maby use the plugin page_dash_access here).

Question 1:
Which method would be the best? Or are there bether ways for solving this problem

Question 2:
Probable I have to use a MVC Framework also (I want to use one)? Like Gaia, Pure MVC, Cairngorm, …
Do you guys recommend me to use it?

- I have used AMFPHP for the data-transfer … using Value-Object classes which I send from PHP to AS 3.0. – And I have used PureMVC for the handling of information. (It was hard to learn PureMVC, but when you’re a little familiar with it, it is easy to handle). You can then write some Proxy’s which can get all the database-information from AMFPHP.

RESULT => A verry fast solution (because AMFPHP is the fastest way to get information from a database and send it to Flash)
