Restlet and Flickr

[Paul J. Lucas]

Has anybody done a Flickr client using Restlet?  If so, details  
appreciated.  Or, failing that, being pointed in the right direction  
on how to do it (what classes to derive from) would be good.

I've been looking at the Restlet code and the thing that strikes me  
as wrong is that the core classes have a small, finite number of  
authentication schemes hard-coded into them, e.g., NMTL and AWS.   
IMHO, there should be no authentication schemes hard-coded.  There  
should be an interface and instead a set of bundled ones, but there's  
no reason, for example, why SecurityUtils should know anything about  
the "X-Amz-Date" HTTP header.
