Well, it *looks* as if you suggest to couple client and server on a shared 
knowledge about a base URI. Working around the URI spec. It also looks as if 
you suggest to couple client and server to JAX-RS implementations because no 
other client framework besides JAX-RS client would ever have the 'overide 
base URI' feature.

I pursued this because I try to avoid such ideas 'leaking' from one of the 
most prominent REST frameworks.

But what if one does not create the link in a request context? E.g. in a 
provider?

+1 on the judgement. Yes, the solution is good and bad :-)

Links in responses *always* have exactly one base URI per the rules in the 
URI spec. (That is our disconnect above, I believe).

(ii) would work if we'd tie Link (or Link.toString()) to a requets context. 
Not sure how/if that works. But (ii) is sort of cleaner, IMHO.
