It will be very interesting for us to compare our bots with the official CS bots... but as for our "plan", if there is one, I believe we can split this in two phases:
1. Each of us developers will still be working on his bot
2. Eventually when the Bots United cooperation will have grown to maturation, lay the slabs for a common work by designing a common, portable, multi-game architecture for our bots - or even better, not limiting to the AI field and build something even bigger (a game perhaps ?) as said in our mission statment on the front webpage of Bots United. But don't hold your breath, it's not for tomorrow yet
