CKS:EBE2.0 has been availale on CodePlex.
CKS:EBE is a Feature?...Noooo...it is a huge application on WSS
The first thing to say about the CKS:EBE is that it is a feature, not a site template. Essentially this means that you can create a standard WSS blog site and use it, later you can add the EBE functionality if you want. This is very useful as it does not require you to make a decision about what type of blog you are going to use when you initially create the WSS site.
Every WSS developer should go through the code and analyze for Best practices.
It has been using for me while doing my current assignment.
This solution mainly focus the wss core things like features that contains all the pages, lists ,new columns,custom themes,storing Media files in Lists,HttpHandler and HttpModules,custom controls,braning files and lot of xsl needed for the EBE.
