title: Flex/PHP: dynamic endpoint URL without services-config.xml
body: <p>how would I change/specify the endpoint URL at runtime in a Flex App which communicates with PHP?
  I always used a services-config.xml so far. </p>
  
  <p>I tried to overwrite the endpoint in the mxml Remote Object, with no success.</p>
  
  <p>I also tried to add a new channel set to the Remote Object, but then I needed to define a destination somehow.</p>
  
  <p>Help much appreciated.</p>
