yes, what Franck and Shannon said.  :)  Honestly, I think we all work in wholly different areas, sectors, ways, and company cultures.  One shop may have a clear delineation between front and back end developers and trust only Java on the back and WS/REST calls only.  Another shop may not have such a clear delineation and use Remoting with CF only, another may use Cairngorm, another laugh at the word, etc, etc..  So really it all depends on the job at hand as well as where you are in a company or not, and may very well all depend on whom the IT Director played golf with last week.

Personally I totally like the magik of RemoteObject, its just freakin kewl the way it works and keeps your model contiguous between the front/back.  I see WebServices for use in exposing your stuff API style to 3rd parties.  If you are building a tool that will 100% guaranteed never expose itself, no need for a WebServices trench coat to march around in, eh? ;)  99.9% of the apps I work on are this case.

Web Services / HTTP services are not built to be the primary backend of your flex applications. Because they are XML based, they have quite a bit more overhead than flex's built-in AMF (Action Message Format). AMF is smaller, faster and uses less bandwidth than XML. AMF is what FDS and ColdFusion 7.0.2 use to communicate to a Flex app.
 
So let's say that your question is narrowed down to "FDS or CF?". Adobe's ideal answer is "yes." They are complimentary to each other, CF allows for wonderful rapid development of Flex apps, and FDS brings some amazing features to the table through it's Messaging an Data Management services.
 
Web Services (SOAP) support is in Flex primarily to consume third-party data, allowing you to add it to your app.
 
Hope this points you in the right direction.

Franck,

I appreciate your respons. When you say Remote Objects/Flex Data
Services provides the most advanced way of interoperating with the
backend, what specifically is possible?

What are the capabilities that I would get leveraging Remote
Objects/Flex Data Services that I would not get (or would be difficult
to implement) with Web services or HTTP services. If there are
resources on the Adobe site that spell this out, please point me to them.

Since we are looking at the different possibilities and we have
somewhat of a blank slate, the more I can go into this with open eyes
the better. I appreciate everyone who responded being willing to guide
someone new to this architecture.

Thanks,
Bob
