I am working with David Reed to put together a simple TeaTime based system - no 3D, just a little counter that can handle replicated text enter events.
I am also working on the architecture of the new UI framework. The main thrust is a generalized UI builder - as opposed to a specific UI. This will make it much easier for people to develop new applications, and new ways to use Croquet. This is the main reason I asked David to factor out TeaTime from Croquet. Basically, I am making so many changes to the places where TeaTime and the UI meet that I decided it would be much better and cleaner for me to target the TeaTime architecture than to have David try to figure out how to make TeaTime work with the relatively arbitrary interface system I built.
