Hello TCPM members,

At the TCPM session on Monday, I intend to take a hum on whether or  
not the WG wants to take on the issue of the definition of the TCP  
Urgent pointer (the last byte of urgent data), and its contradiction  
with most TCP implementations (the first byte after the urgent data),  
as documented in draft-gont-tcpm-urgent-data-01.txt.  It would be nice  
to get a feel from the mailing list prior to the meeting.

Please reply whether you are in favor of, against or have no opinion  
on adopting this as a WG item.
