Not only this, but for security purposes you'll want to have your data
tier CFC's w/ an access modifier of package and have "wrapper" or
"proxy" or, my personal favorite, "business delegate" CFC's expose your
data tier as webservices (which is the same thing for flash remoting).
For plain html I've been known to do this:
<cffunction name="listBox" output="false">
<cfset var r = "" />
<cfsavecontent variable="r">
<select name="foo">.. You get the idea..
</cfsavecontent>
<cfreturn r />
</cffunction>
And just an fyi: Flash 7 has enhanced html support in it's textfields--
a good definitely a good idea to keep flash in mind as it evolves..
