I wonder if this would work for Emerge as a place for people/teams to share ideas and coalesce into proposals:
alphaWorks Services | ThinkPlace | Overview
ThinkPlace is a Web application for facilitating innovation through idea generation, collaboration, and refinement. ThinkPlace is unlike a suggestion box; when used within a company, it shares ideas within the entire company. By providing a common place for sharing, refining, and recognizing ideas, ThinkPlace encourages all employees to innovate and to collaborate on further improvement of the ideas. Even if employees don’t have an idea to post, they can look around, collaborate, rate others’ ideas, or find ideas for their own use. ThinkPlace also invites suggestions for improvements.
ThinkPlace provides customization options, including the ability to tie into existing LDAP-based mechanisms for identifying users as they log in to the application.
