Ariaware have been very busy lately, they are doing great things for us flash geeks. Recently they released an open-source Rich Internet Application Framework named ARP, which is a pattern based, structured code base written with Actionscript 2, that makes it simple to create scalable and maintanable Flash Applications. Form Based development is also possible although i personally would stay well away from Forms for various reasons im sure you all know by now. Definetley worth a look and you could even help take this framework further.
