One of the things we've discovered over the course of our investigations here is that overloading multiple functions on a single number is an often regretted decision.

On the other hand, in order to get good performance one sometimes /must/ fold together things.

That is to say, a highly multi-"dimensional" architecture - where every little concept is called out separately - may be as "bad" as one with too few "dimensions". The trick of course is to find /just/ the right balance.

E.g. if you separate out locators from end-host IDs you may solve problems with the scalability of communicating the state of locators, but you substitute for it the problem of communicating the state of end-host IDs. Etc..
