The twice-weekly military convoy from Morocco to Mauritania is no more. Overlanders are now free to make their own way directly to the border as of start of Feb. 2002 with no formalities being necessary in Dakhla.
We found out the hard way, arriving the day after the last convoy and trying to hitch a lift.
The obvious repercussion is that drivers no longer need to make the 50km diversion down to Dakhla and may go direct, making hitching lifts down all that more difficult.
Camping Mousstaffa is still the best place in Dakhla to find a ride, but be wary of Mauritanians trying to scam you with tall tales and high prices to get you there. They're on the scent, but lifts are still possible as we found out.
