You are going to hear over and over again that users don't want to  
manage anything.

Regarding unique IDs, they should be able to assume the IDs are unique  
because underlying layers take care of it for them.

Regarding changing providers, with a decent Loc/ID split solution, IDs  
don't have to change when you change service providers.

If you have variable length IDs, then remote sites will have to  
capable of parsing the different lengths.

I don't think it's a good idea. We have enough fish to fry and this  
flexibility is not really providing any real value.
