Neil Hastings has proposed Block Entities Are Awesome for DrupalCon Denver:
The bean module allows the creation of fieldable block entities. Similar to node types, different block entity types can be created with different fields and configurations. This allows your editors to create blocks with the ease of creating a node, without needing to write code or deal with a complex admin.
The session will demonstrate how to create block types, both in code and in UI. The session will also show different ways of using block entities, including the Blockreference module, which allows editors an easy-to-understand way to place blocks within a node, and demonstrate how Beans can be used to provide an alternative method of creating Views-driven blocks.
If you're interested in this session, please vote on it. And if you have comments or questions regarding the proposed session, please comment below. Even if it isn't accepted at DrupalCon Denver, Neil may be presenting it elsewhere.
