You only have to place the swf-file on a server (free-hosting..) and edit the embed-Tag. Finished! 
With the proxy-feature, you are allowed, to feed your RSS-Stream from anywhere. (Myspace etc.)
You also can get your RSS-Feed from free hosts wordpress.com blogs. (without upload or edit the template files or stuff like that.) 
You dont have to place a crossdomain.xml (thats useful, because in some cases thats not possible: if you dont have enough permissions.. etc) on your Server! (you can, if you want to disable the proxy-function. But you dont have to! 🙂 )

If you’re running WordPress behind a proxy, chances are that the IP address of the user browsing your site won’t show up, instead WordPress will see the IP address of your proxy server. Proxy Real IP sets this straight by looking at the HTTP headers that the proxy sends.
Proxy Real IP looks in the following HTTP headers: 
X-FORWARDED-FOR, X-FORWARDED, FORWARDED-FOR, FORWARDED, X-REAL-IP
Proxy Real IP sets the user’s IP address to the first HTTP header defined that matches a simple regular expression of an IP address (123.123.123.123).
Proxy Real IP also sets the $_SERVER[‘HTTPS’] variable correctly when running behind a proxy so that WordPress can determine whether or not the proxy connection is over HTTPS. It looks to the HTTP_X_FORWARDED_PROTO PHP server variable to determine this.

Proxy Real IP

Proxy Real IP is a simple plugin that sets user's IP addresses correctly when running WordPress behind a load balancer or other proxy.
