So I believe that the IPR stuff of gdiff is settled.
OTOH I want to repeat my recent binary diff proposal with 
	"add from diff" <number of octets> CRLF <octets> CRLF 
	"copy from resource" <position> <number of octets> CRLF
c 5 5
a 2
c 0 5
I can't imagine that there is any IPR on such an simple and obvious format.
OTOH I think it's easy to implement and powerful enough to be of value.
If nobody disagrees we could add gdiff and this binary patch format to one
of the existing drafts.
I'm currently validating my ObeDAV client with subversion and apache.
By chance anybody from subversion listening who knows whether subversion
uses any diff format when working with or without apache ?

Cheers, Edgar
