CF8 - Flex-3 remoteObject configuration

I am sure I have done this right but nothing I do seems to work...

I get an error asking for a <gatewayid>. Not sure where I need to apply that and I have never seen any reference to it in any example code. If I pull the <gatewayid> out of the config file then LCDS won't start because "COLDFUSION... Don't know where to send messages"

The error is;
faultCode:Server.Processing
faultString:'Message header 'gatewayid' required in message when sending to destination 'ColdFusion''
faultDetail:'null'

I am running this on a LINUX system (blackmagic), CF-8 is located @/opt/coldfusion8/
My CFC is the standard Hello World cfc and I have it @ /opt/coldfusion8/wwwroot/CFC/hw.cfc

Any ideas will be greatly appreciated.

The FLEX script looks like;

<mx:RemoteObject id="helloWorld"
destination="ColdFusion"
source="CFC.hw"
fault="faultHandler(event)"
endpoint=" http://blackmagic/flex2gateway/"
>

<mx:method name="GetHello" result="GetHello_handler(event)" fault="faultHandler(event)" />
</mx:RemoteObject>

services-config.xml (abbreviated) looks like;
