I've been skimming, and it seems like it would be possible to change
slimfx to look for the socket policy file elsewhere. The fact that 843
is less than 1024 is apparently intentional - see
http://www.adobe.com/devnet/flashplayer/articles/fplayer9_security_04.html.

However, it seems that there is another relatively easy solution for
Linux -- running a perl or python script (as root) that will serve up
the socket policy file on port 843, or running such a script through
xinetd. Sample scripts are provided at
http://www.adobe.com/devnet/flashplayer/articles/socket_policy_files.html.
(This link was actually mentioned in a previous post by EFP).

The actual policy file served up should be this:

<cross-domain-policy>
<site-control permitted-cross-domain-policies="master-only"/>
<allow-access-from domain="*" to-ports="9090"/>
</cross-domain-policy>

I assume that anyone with a working knowledge of Linux would be able to
set this up pretty quickly. Though maybe it's also necessary on OS X?
I'm not running Linux at the moment, but maybe someone could try it
out?

It's unfortunate that there are such a daunting number of steps to get
this thing running at this point. Not *so* many steps, but more than
there should be. If I get a chance, I'll look into loading the socket
policy file from a different port, and posting a modified version of
both slimfx and the socket policy plugin. Can't promise that'll be any
time soon, though.
