You should re-write yum so that it searches for a different [random]
mirror for each rpm it needs.
That way the load is spread.
I could run a mirror for you, I would be willing to donate 1/4 meg
uncontended when my 2 meg feed goes in in december....
I don't have much bandwidth spare but I want to do my bit...
