1. You can access http services or web services on another server without
FDS - but there are a few caveats. First, you must be able to place a crossdomain.xml
policy file on the webservices server and that policy file must grant access
from the other domains that host your SWFs. However, if your webservices
server uses HTTP status codes other than 200 for faults then you cannot use
the Flash Player directly to communicate with these services due to limitations
in the Firefox / NS plugin API that stop the player from getting access to
the SOAP fault body in the response (this problem is avoided by the FDS proxy
Note that the crossdomain policy is required for accessing remote objects
on remote servers too.
2. To access Remote Objects without FDS, you could use ColdFusion, or you
could look for posts by customers who connect to one of several open source
servers out there that can translate RemoteObject requests to various types
of server application languages, like PHP, C# and Java.
