I think we will need to put a copy of the image in every region where
we want to run things.  There will be a probably pretty small cost for
storing it.  We could probably get away with only Singapore and
Virginia.

My original motivation was actually that us-east-1 was having trouble.

I have tested making a new (private) ami is ap-southeast-1 and then
booting it there.  It is about 100ms closer than the US (I'm surprised
it's not more.)  It is distinctly faster for interactive use.
