This is a neat trick, and definitely saves some bandwidth if your 
are at the far end of a very narrow pipe.  However, it's not for 
the faint of heart!  A lot depends on getting the timing exactly 
right, and that's not a trivial task.

It's a game for trained professionals... Definitely in the class of 
"Don't try this at home, kids!"

Disk is cheap.  Doing the default thing -- duplicating the yum 
headers and packages per machine -- is definitely the safest plan.
