We're off in the woods again.  Let's keep these two principles in mind:

  * The DNS resolution mechanisms are not expected to resolve, let alone
    secure names ending in .ALT.
  * How other resolution mechanisms secure names is their affair.

Therefore, any collisions that occur within .ALT are for alternate 
resolution mechanisms themselves to resolve (or not, as they see fit).  
Which brings me to this:

... from the perspective of DNS.  Whether it is "yours" or "mine" from 
the perspective of GNS is a matter for GNS to resolve (for example).
