On the Ruby Object Teams page on sourceforge there's a link called "Home Page", 
which leads you to http://objectteams.org

My first impression is that Object Teams is a very useful paradigm. It "allows 
the programmer to encapsulate the interaction of a set of objects (roles) into a 
compound object (the team)". I've never been convinced to really start using 
AOP, but I'll definitely give the Object Teams concept a try.
