+			V9FS: 9P2000 for Linux
+			======================
+
+ABOUT
+=====
+
+v9fs is a Unix implementation of the Plan 9 9p remote filesystem protocol. 
+
+This software was originally developed by Ron Minnich <rminnich@lanl.gov>
+and Maya Gokhale <maya@lanl.gov>.  Additional development by Greg Watson 
+<gwatson@lanl.gov> and most recently Eric Van Hensbergen 
+<ericvh@gmail.com> and Latchesar Ionkov <lucho@ionkov.net>.
+
+USAGE
+=====
+
+For remote file server:
+
+	mount -t 9P 10.10.1.2 /mnt/9
+
+For Plan 9 From User Space applications (http://swtch.com/plan9)
+
+	mount -t 9P /tmp/ns.root.:0/acme/acme /mnt/9 proto=unix,name=$USER
+
+OPTIONS
+=======
+
+  proto=name	select an alternative transport.  Valid options are 
+  		currently either unix (specifying a named pipe mount
+		point) or tcp (specifying a normal TCP/IP connection)
+  
+  name=name	user name to attempt mount as on the remote server.  The
+  		server may override or ignore this value.  Certain user
+		names may require authentication.
+
+  debug=n	specifies debug level.  The debug level is a bitmask.
+  			0x01 = display verbose error messages
+			0x02 = developer debug (DEBUG_CURRENT)
+			0x04 = display 9P trace
+			0x08 = display VFS trace
+			0x10 = display Marshalling debug
+			0x20 = display RPC debug
+			0x40 = display transport debug
+			0x80 = display allocation debug
+
+  maxdata=n	the number of bytes to use for 9P packet payload (msize)
+
+  port=n	port to connect to on the remote server
+
+  noextend	force legacy mode (no 9P2000.u semantics)
+
+  uid		attempt to mount as a particular uid
+
+  gid		attempt to mount with a particular gid
+
+  afid		security channel - used by Plan 9 authentication protocols
+
+  nodevmap	do not map special files - represent them as normal files.
+  		This can be used to share devices/named pipes/sockets between
+		hosts.  This functionality will be expanded in later versions.
+
+RESOURCES
+=========
+
+The Linux version of the 9P server, along with some client-side utilities 
+can be found at http://v9fs.sf.net (along with a CVS repository of the 
+development branch of this module).  There are user and developer mailing
+lists here, as well as a bug-tracker.
+
+For more information on the Plan 9 Operating System check out
+http://plan9.bell-labs.com/plan9
+
+For information on Plan 9 from User Space (Plan 9 applications and libraries
+ported to Linux/BSD/OSX/etc) check out http://swtch.com/plan9
+
+
+STATUS
+======
+
+The 2.6 kernel support is working on PPC and x86.  
+
+PLEASE USE THE SOURCEFORGE BUG-TRACKER TO REPORT PROBLEMS.

It's also useful to put some actual content in your subjects.

So instead of:

[RFC][2.6 patch 0/7] v9fs 2.0-rc5 - 9P2000 Support For Linux 2.6
[RFC][2.6 patch 1/7] v9fs 2.0-rc5 - 9P2000 Support For Linux 2.6
[RFC][2.6 patch 2/7] v9fs 2.0-rc5 - 9P2000 Support For Linux 2.6

Do:

[RFC][patch 0/7] v9fs: the Plan 9 network filesystem (2.0-rc5)
[RFC][patch 1/7] v9fs: documentation, makefiles, config
[RFC][patch 2/7] v9fs: core protocol bits
[RFC][patch 3/7] v9fs: core filesystem bits
[RFC][patch 4/7] v9fs: helper routines
[RFC][patch 5/7] v9fs: the bits that touch VFS

This gives us much more information about what is where, and gives
hints of what patches I might be interested in looking at.
