Rob I do something similar, but not sure if it's what you're after.
<cfinput name="mobile" type="Text" onChange="if (document.myform.mobile.value.length > 4){ColdFusion.navigate('mobileCheck.cfm?x='+document.myform.mobile.value,'filterWindow',mycallBack,myerrorhandler)};"> So a CFWindow to the side of the form is updated with a list of possible matches for what is typed into the mobile field. If you see the match you want then you click on a link in the cfwindow and the form is populated.
