We have recently published an article on API changes that we want to make in next version of Entity Framework in order to enable more N-Tier scenarios. Getting this right is very important to us and we're interested in getting as much of your feedback on the proposed design as possible.

Please read and comment on the article at: http://blogs.msdn.com/efdesign/archive/2008/11/20/n-tier-improvements-for-entity-framework.aspx
