Hi Stian, We haven't forgotten about your suggestion, just dealing with a long email backlog :)
It is perfectly possible to optimize the internal algorithm so that getRepresentation(Variant) is never called when the variant's tag matches the one provided by the client. I've entered a RFE to keep track of it: http://restlet.tigris.org/issues/show_bug.cgi?id=319 As it changes the observed behavior a bit, it should only go in Restlet 1.1, IMHO.
