 To get Fedora working well on Amazon's EC2 cloud computing service ![1]
 the Cloud SIG is working on creating yum mirrors inside Amazon's network.
 Doing so provides a number of benefits:
  * Faster updates for users
  * People with hundreds of Fedora instances don't overload other public
 mirrors
  * No data transfer costs for users or those who fund the EC2 mirrors
 (traffic within a given cloud region is free)

 Unfortunately, data transfers are only free if they stay within a given
 region.  This, combined with the fact that EC2's IP addresses freely roam
 between regions, makes normal IP-based direction via !MirrorManager
 impossible.  We therefore need another way of directing clients toward the
 mirrors that reside within their own regions.

 Our list of proposed solutions to this are posted in the "Client Access"
 portion of my overall proposal for EC2 mirror infrastructure ![2].  Could
 you folks (a) offer any feedback, or (b) choose which solution would be
 best?  I apologize if this is more of a FESCo question; I can take it to
 them if that would be better.
