Maybe, but you can quite effectively hide a Corba wrapper from an application developer, so the complexities can be left to specialists. Using the example of java - RMI is built on IIOP, if a simpler platform does come along there is every chance that Corba will still be at the heart of the platform (?).

What are your feelings on the current suggested interfaces, GetLocation, WhereIsIt, WhereIsItInTermsIUnderstand, BuildPathway, Who'sThere?
I'm not clear as to what interface they actually address. I can see that GetLocation, WhereIsIt, Who'sThere are useful for a location server but is it the role of a location server to provide services such as WhereIsItInTermsIUnderstand, BuildPathway these seem to be value added services.The implication is that a mobile user will interface directly with a location service - I can't see the usefulness of this. I guess the confusion lies in exactly what reference model is being used. Do see a need for a formal model or do you think that it is generally aggreed and understood?

What about time stamps?
