Asylum BB tag for Flash movies project

Abstract : Idea and technical considerations
Related : Estimate of the need

Introduction

The goal of the project is to safely embed Flash content inside the forum called Ozone Asylum

Considerations

1. Mapping the movies to (xhtml) : Flash Satay vs Flash standard vs SWFObject
2. No sound in movies - can be done using stopAllSounds cleverly (or other action script methods)
3. Preventing XSS attacks - can be done using the Flash sandbox (disabling fscommands for one)
4. Usage and integration of the crossdomain.xml policy file
5. Is an additional "Flash proxy" useful and/or required?
6. Setting a maximum size?
7. Are other constraints required?

The answers appear to be :

1. XHTML is the target. Flash standard is not cross browser. SWFObject is convenient, but requires ugly nesting of script tags inside the transformed code.
   Satay is convenient, with drawbacks that do not seem to apply to the Asylum - since the goal is not to stream large medias like sound. Video may be needed though - testing required.
2. As stated above : all sounds should be muted inside movies. Several references indicate it can be done and how to do it.
4. Appears to be required, in order to provide control of the source domains and referrers for embedded content.
6. Proposal : 640x200 maximum size when remapping the swf item to xhtml code.
