Shaping though shouldn't absolutely kill a service. The problem is that the overall quality has dropped in that before you would connect but receive (rightly so) a shaped speed. I don't think anyone contests that part. The main issue is not that the speed has dropped, in fact if a tracker has already provided a seed/peer list everything works perfectly fine. The issue is that the trackers themselves, a lot of which are http trackers i.e. it is connecting over the standard 8080 port, are timing out or for a variety of reasons, simply not returning the required data.
It may though be just another function of the Skype issue + latency issue (http browsing was poor, http downloads weren't)
