Setting ETag after MessageBodyWriter has serialized entity

Subject: Setting ETag after MessageBodyWriter has serialized entity
Date: Thu, 9 Feb 2012 18:50:47 +0000 (GMT)
I would like to set the "ETag" header on the response based on a hash
of the serialized entity.  After created the hash I would also like to
check if it matches the "If-None-Match" request header, and if it
matches return a status of 304 with a empty entity.  
I got it so I can create the hash and set the "ETag" header in the
MessageBodyWriter, but I am unable to change the response status within
the MessageBodyWriter if the "ETag" matches the request  header
"If-None-Match".  Does anyone know how to accomplish this.  
I also tried using a ContainerResponseFilter, but that did not work
because it is called before the entity is serialized.  Thanks!
