To be perfectly honest... I wanted to be able to have all users from my ISP as local, because transfers between them don't count to my net connection limit, unfortunately I'm separated from them a) by my home router, they are also scattered on few LANs so broadcasts definitely won't reach them. Also I'm not very found on 1.7.2 decision to block LDP for private trackers :/ It would also be good if uT would treat local peers with priority. It's no big deal since it doesn't disturb normal data exchange between peers from the Inet. This would really shorten any download when working together with some friends from my ISP beyond any other tricks (because no tricks can extend physical limitations of ones Inet connection). Shouldn't good P2P app always pick the best routes to download efficiently? Currently dumb tracker won't always return the best peers (escpecially if there are hundreds or more) and ut won't even know witch to pick in the first place - that is witch actually belongs to my ISP, can skip UL/DL limits and should be prioritised (and they should be).
