I started a wiki page on what to do next in the LunarGLASS project at http://code.google.com/p/lunarglass/wiki/NextSteps
Discussion could be posted there at that page, or in [email protected]. We'll be doing actual on-going planning and development through the code.google site, and barring some possible permissions/access problems, others are welcome to join in.
