I think, i know(and others, who use this method) better what i'm doing, and why i am doing it.
So, i tell you once more - community think, that this is useful.
People, who say "Hey, man! I have server, and rsync installed, add me please to the list of 3rd party mirrors" know what they do.
If they offer this service - they think it helps. If they would have 'tiny pipe'(or something else tiny) they wouldn't do it.
So, i still don't understand why opinion of community ignored.
