Hey All,

For various reasons, Rackspace has a need to allow customers to request placement in the same zone as another server.  I am trying to figure out if this is generically useful, or something that should be outside of core.  The idea is that if you don't specify an affinity ID one will get returned to you when you create the server, and you can use that ID to add additional servers in close proximity to the first.

What do you think?  Is this useful enough outside Rackspace to be in core?  Alternatively, we can write it as an extension so as not to clutter core.
