We have had similar discussion about this. Dominik added earlier
a ITransientLocation (I guess) for such a usecase. Jim suggest to 
remove this part. But I still think it's important to know if you 
have a real ILocation or a transient ILocation which you get with 
LocationProxy.

It whould be nice to have a ITransientLocation(Interface)
and a ILocation(ITransientLocation).

Persistent location are only supported by ILocation and not by
ITransientLocation.

What do you think?
