Flex and ColdFusion web services

Question

I have a simple CFC created that encompasses a function that
has a query. I want to be able to use the web service in my Flex
app, but I am having issues with getting the information from the
CFC.
My function is simple:
<cffunction name="listBySubject" access="remote"
returntype="query" output="false" hint="I grab the newest
stories">
<cfargument name="subject" type="string"
required="yes">
<cfquery name="list" datasource="#myDataSource#">
SELECT linktext, story, photo
FROM pressreleases
WHERE rss_feed = <cfqueryparam
value="#arguments.subject#" />
OR rss_feed2 = <cfqueryparam value="#arguments.subject#"
/>
ORDER BY releaseDate DESC
</cfquery>
<cfreturn list>
</cffunction>
How can I modify that to use in a Flex app's
<mx:WebService>? Do I have to use cfsavecontent and return
XML or can I keep it a query and use it with an ArrayCollection?
Something like:
<cffunction name="listBySubject" access="remote"
returntype="xml" output="false" hint="I grab the newest
stories">
<cfargument name="subject" type="string"
required="yes">
<cfquery name="list" datasource="prmc-media">
SELECT linktext, story, photo
FROM pressreleases
WHERE rss_feed = <cfqueryparam
value="#arguments.subject#" />
OR rss_feed2 = <cfqueryparam value="#arguments.subject#"
/>
ORDER BY releaseDate DESC
</cfquery>
<cfsavecontent variable="storyList">
<magStories>
<cfoutput query="list">
<magStory id="#ISBN#">
<linkURL>#XMLFormat(linkURL)#</booktitle>
<story>#XMLFormat(story)#</teaser>
<photo>#XMLFormat(photo)#</price>
</magStory>
</cfoutput>
</magStories>
</cfsavecontent>
<cfreturn storyList>
</cffunction>
Locally I can use RemoteObject all day with the way it is
normally, but since UofMichigan has BlueDragon, I am forced to
convert my apps to WebServices.

No in flex you call the webservices like:
<mx:WebService id="webService"
wsdl="
http://www.flash-mx.com/ws/months.cfc?wsdl">
<mx:operation name="getMonths"
resultFormat="object"
result="getMonths_result(event);"
fault="getMonths_fault(event);" />
</mx:WebService>
