I'm pretty sure a regular user can create a server group and specify the 
anti-affinity filter.  And a regular user can certainly specify --min-count and 
--max-count to specify the number of copies.

Normally only admin-level users are allowed to know which compute nodes a given 
instance is placed on.  Why do you need to track which compute nodes the 
instances are on?
