Instance number strategy


I am interested in developing an instance numbering strategy and would appreciate feedback from anyone who has developed a tested numbering scheme.

I work at a large installation with dozens of SAP instances including CI, app servers and Web Dispatchers. Since most of the these systems are on separate servers or virtual containers, there has been no conflict with ports if the system numbers are the same. Going forward, we are facing installation of additional DEV and QAS landscapes and I want to choose instance numbers wisely since they aren't easy to change.

Also, Adaptive Computing provides the ability to move instances to different hosts easily but only if the the instance numbers are unique to prevent port conflicts.

Are there any other technical considerations beside duplicate ports when choosing system numbers?

I would appreciate any feedback about your number rules or polices.
