Icarus Interstellar is a “non-profit organization dedicated to achieving interstellar spaceflight by the end of the century”. They have organized a Kickstarter campaign to support a meeting this summer to discuss the gamut of issues related to deep space and interstellar spaceflight:

Imagine collectively experiencing the progressive thoughts and unencumbered designs of the world’s leading spacecraft designers, engineers, and astro-theorists. Picture for a moment, attending a forum where scientists, physicists, engineers, researchers, urban designers, representatives from international space programs and present-day commercial space operators, as well as popular and well-known interstellar speakers and space journalists share their visions for how the future of spaceflight and exploration may unfold.

This is the vision behind the Icarus Interstellar Starship Congress, to be held August 15-18, 2013, in Dallas, Texas. The aim is to bring together the interstellar community to foster discussion surrounding the development of deep space exploration within the next several decades, and how we may move humanity toward becoming an interstellar civilization.
