+The issue is that we have 2 types of mirror admins :
+
+- there is some of them who are hobbyist/enthusiasts, that use their own
+server for that, and that mirror only one or 2 distros, and that may not
+do it for their job or as part of their job. I think for example
+Wolfgang would be in this category. They want to help us, but they may
+have slightly limited ressources. But they can have time to tweak the
+mirroring to fit what they can offer to us.
+
+- on the other end of the spectrum, we have people who manage lots of
+mirrors, with more bandwidth and bigger servers, more , but maybe not
+more time. Ie people that does it as part of their job, with the
+associate increase of ressources and work that come with a job. 
+
+So admins that are more of the type 1 are likely ok with following
+lists, giving input, tweaking rsync scripts, etc. They are the one that
+could help us by giving stats or stuff like that, because they have the
+time. But that's also people who may have more trouble ( because of
+lesser ressources )
+ 
+Type 2 would prefer to not have too much to do because they may have
+better thing to do. Ideally, they set up and do not touch for the 10
+next year and that's ok. 
+
+So we need to take in account this divide.
+
+We can't have just one type or the other, but in both case, a simpler
+mirroring process will benefit to everybody.
