I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. The draft defines a URI for rsync, and it refers the reader to the detailed security considerations of RFC 3986 (Uniform Resource Identifier (URI): Generic Syntax), after pointing out that some of those considerations do not apply. This appears to cover the security issues. David
