Micro-Space has posted about progress on several fronts in the Google Lunar X PRIZE Teams site. Some of the progress sounds like it's for the Lunar Lander Challenge. It sounds like the LLC work is part of their plan of progressively demonstrating hardware success before looking for funding for the next level.
Meanwhile, LunaTrex was apparently one of the Google Lunar X PRIZE teams that Will Pomerantz mentioned as having been at the National Space Symposium. On the Teams site, they discuss some of the networking they did at the Symposium.
