Just a few questions about these:
I see the main point is not listed as being bandwidth (despite what other
people say about the huge importance of compact=1 suggesting that trackers
are bandwidth limited) or even reliability (the solution has a single point
of failure tracker hub apparently too, rather than peer to peer tracker
solutions, though it will add some extra reliability), but number of
This is a bit surprising to me as the limiting factor, how many connections
are we talking about? And doesnt UDP tracker solve this by being
connectionless? Or are there other problems with udp, or is it just not
