Excellent, this is basically the information we would also see when tc stab is used, and being the actually input in the (maybe indirect) transfer time calculations is the best number IMHO for sanity checking...

	Again, that sounds great, in your opinion now with the overhead/size accounting put on new footing and Toke's xstats work are we closer to being mergeable upstream? Any other blockers pending improvements?
