Access Etag in a list

Hi,
	If I access a view or list in my browser I see an Etag is set. Is it  
possible to access the value of the Etag set for a view in a list  
call, or access the Etag CouchDB sets for a list? I can't see this in  
the wiki docs or the book and the head and req passed into the list  
function don't contain it.
Cheers
Simon

The Etag is calculated based on the function body and the view index
sequence num. If it matches, CouchDB doesn't even need to run the JS
code.

There's not a good reason why it's not in the req object, except I
can't see what it'd be useful for
