nevermind - found the solution!
ended up with:
<cffunction name="checkPermission">
<cfargument name="path">
<cfif IsDefined('session.currentUser.permissions.' &
arguments.path)>
<cfif evaluate('session.currentUser.permissions.' &
arguments.path)>
<cfreturn true>
<cfelse>
<cfreturn false>
</cfif>
<cfelse>
<cfreturn false>
</cfif>
</cffunction>
(Never used evaluate() before, heard it was bad..?)
