+Ok, I would say that in most respects we agree.
+1) The mirror site should take _whatever action they feel is 
+appropriate_ to ensure that they are not overloaded, including 
+restricting the number of connexions per user, bandwidth quotas, etc.
+
+2) A non-dedicated mirror (in most cases) should do whatever is 
+necessary to give priority to its non-mirror activities.
+
+3) Downloaders should generally use multiple mirrors if they use 
+multiple connexions.
+
+and probably many other points that don't come to mind.
+
+However I feel that
+4) It is reasonable for downloaders to use multiple connexions per 
+mirror, as long as they don't bypass the controls put in place by the 
+mirror.  Not only reasonable, but actually desirable in terms of using 
+otherwise unused download capacity that occurs from time to time, and 
+thus enhancing general download access.
+
+There is another factor that may not have been considered.  Many 
+downloaders will be slowed by their internet access or other non-mirror 
+factors, which will very much increase the likelihood that mirrors have 
+unused bandwidth at various times.  Increasing the utility -- from both 
+sides -- of multiple connexions.
+
+BTW, I understand very well the complexity and frustration that can be 
+associated with administering a site, be it a mirror or otherwise. 
+Especially for configuring appropriately.
+The trick, of course, is getting there :)
+
+In any case, we can disagree on some points and still contribute 
+together, in our various ways, to Mageia.
+That is the most important factor.
+
+regards :)
