Chatroom in flash

Anyone have any exp with this? In playing with my using chatroom I having my system compatible with this would be usefull ( and cheaper for some people ) and just wanted some input?

do u think I can use a .NET platform(VS.NET w/ ASP.NET app) w/ its db backend is ms sql server 2000 aside from java/php-mysql-postgre-apache server i think in order to work with my server?

cause i already have a flash comm server 1.0 but i dont have a ver 1.5 and i also have a flash remoting mx for .NET i dunno if ever might take time to code using that in my profile and chat app?

which do i prefer the best and an easy way in creating the chat app using flash?

a.) ASP.NET MS SQL server 2000/ms access
b.) PHP postgre/mysql

it can be done with only php and flash…
but you need full shell acces of your server to use this method…

look at my footer, click on chat, and send me an pm when your on…
