1. I think it is a rare enough occurance that ARIN should
   not be spinning cycles to develop and test the filter.

2. I would guess that ARIN already disallows multiple
   *reassignments* for overlapping networks of the same
   and different sizes.  (We have an example of reallocations
   in this case.)  Someone on the ARIN staff can confirm
   that.

3. I know of at least one valid reason where an organization
   would reassign themselves the same block that was
   reallocated to them.  (Goes back to the flexibility
   concern that keeps coming up for a different topic.)

4. There might actually be a reason (however poor it may
   be) for someone to reallocate to themselves the same
   network more than once under the same org ID.  I can't
   think of a really good reason, but I can think of at
   least one poor one.
