The IBTA specs are not API specifications.  They define semantics and wire 
protocols.  As for what was envisioned which guided the spec, most data 
center management applications understand a variety of management objects 
that represent various IP based attributes.  A GID is close enough to an 
IPv6 address that many of these objects could be easily modified via a 
plug-in such that the IB would have been easily slid into the associated 
management applications.  Investigations occurred, e.g. in to providing the 
necessary plug ins for OpenView, Tivoli, etc.  This is one area where IB is 
insufficient in terms of a viable ecosystem since there really isn't any 
way to manage IB in the enterprise without requiring significant amounts of 
training and a new tool chain to be deployed.
