given that last discussion is 2yrs ago and you said actual implementation already biased from original spec, it'd be difficult to judge whether current change is sufficient or just 1st step. Could you summarize what have been changed from last spec, and also any further tasks in your TODO list? at least just map/unmap operations definitely not meet XenGT requirement...
