A Flash Video Server and Flash Security

Question

We are using Flix and Squeeze to create new Flash 8 SWF
movies from our AVI files. Short 1 - 2 minute tutorials.
We would like to be able to save them on our server and allow
different websites to add a custom Flash Player to their site and
watch these videos from their pages. The player gets an XML
playlist of up to 50 videos and we would like to be able to play
one or more of the movies on the webpage of our partner.
However, this seems to cause (2) security violations in the
Flash 8 environment. We need to add a crossdomain.xml file on our
server to allow other sites to access our swf files, and
apparantly, we also need to use actionscript
System.security.allowDomain() to allow the parent SWF player to
control the video in the player (stop, start, pause, etc.).
Does anyone know more about this situation? How can we add
the allowDomain() to an SWF created by Flix or Squeeze, or is there
another way to communicate the allowDomain(). Can we pass anything
in the XML itself, does it have to be in the SWF.
In Flash 8, every SWF must communicate the allowDomain(). In
earlier versions of Flash, only one SWF needed to open the sandbox
for any other SWFs from that domain.
Did we misunderstand the requirement? Our Flash developer
can't figure out a way to make this happen, but I am sure others
have been able to make it work. Otherwise, how can any of the Flash
hosting companies allow these movies to be downloaded off of their
sites.
Any advice would be appreciated...

Hello Thanks for reply,
           Its many to many chat and every one can speak and listen. There may be 10-12 users in a room  at a time and also the number room can be several.
So what type of server I should take. Some delay is acceptable.
