Chandler appears to be virtually a dead project or at least a very slow moving one. The last update of any sort to Chandler Desktop was almost a year ago, and their last blog entry not much more recent. If it were me, I wouldn't put a lot of effort into adopting Chandler absent any strong evidence of a strong developer community.
