Answer 1

You may need to setup a crossdomain.xml to allow the one SWF access to the other in the production environment.

Answer 2

Here's a couple things. Remember your security policy document and your SWF publishing settings. I hope these resources help.

Cross Domain Policy "Use master-only"

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd"&gt;
<cross-domain-policy>
  <site-control permitted-cross-domain-policies="master-only"/>
  <allow-access-from domain="*" to-ports="*"/>
</cross-domain-policy>

Your SWF Publishing Settings
