Thank you Mathieu, I am looking forward to 0.11 :)
In case this is helpful to you or others: after more than a week of waiting, ZED support finally partially replied to my questions regarding the ZED's specifications. They said that the depth accuracy is "1mm @1m and 1.5m @15m". I don't know if the relationship between the depth accuracy and actual distance is linear but if it is, then at 2 meters the accuracy is already ~11cm and at 6m it is over half a meter.
So I am not very optimistic about using ZED by itself. But I hope that if depth data is taken from the Velodyne, the accuracy can be acceptable. Given ZED's pretty bad accuracy at larger distances, would it be better to use some other camera that gives better resolution which I am guessing would allow better feature detection?
