Multiuser programming questions

I'm trying to create an extremely specific form of multiuser application on Adobe Air for Android. I want to allow up to ten users to connect to a swf that updates whenever one of the users makes a change. It doesn't need to be high performance and only needs to share simple ints and strings. I'm trying to find the most efficient way to set this up and have gotten nowhere. All of the tutorials I have seen have been entirely too complicated for what I'm trying to achieve and all of the open-source solutions I have found provide way more functionality than I need.

I don't really need to be hand-held, so if someone could just point me at an article or something I'll be on my way.

Thanks
