The ability to set and send form parameters with the same name is available with URLVariables though it's not quite documented very well (at all?).

Below are 4 examples of setting 2 values with same parameter name. The first example results in 1 parameter. The rest result in 2 parameters as expected.

 
// results in 1 parameter
var urlVarsA:URLVariables = new URLVariables();
urlVarsA["foo"] = "Hello";
urlVarsA["foo"] = "World!"; // this overwrites the previous
trace(urlVarsA); // foo=World%21
 
// results in 2 parameters as expected
var urlVarsB:URLVariables = new URLVariables();
urlVarsB.decode("foo=Hello");
urlVarsB.decode("foo=World!"); // decode() has logic to detect existing params
trace(urlVarsB); // foo=Hello&foo=World%21
 
// results in 2 parameters as expected
var urlVarsC:URLVariables = new URLVariables("foo=Hello&foo=World!");
trace(urlVarsC); // foo=Hello&foo=World%21
 
// results in 2 parameters as expected
var urlVarsD:URLVariables = new URLVariables();
urlVarsD["foo"] = ["Hello", "World!"]; // Arrays are special to URLVariables
trace(urlVarsD); // foo=Hello&foo=World%21
