No patents were announced.

Michael announced that, with team agreement, no meetings would be held 
until January 7, 2009.

The team reviewed the distributed Touchstone 2.0 draft.

Bob noted that having [Version] and [Number of Ports] as a "1-2 pair" still 
seems like a good idea (see p. 21 of the markup draft).  He also stated that
the placement of the options line versus other lines still needs settling.

The team suggested the following changes and updates in the markup copy:

p. 22 - example is missing [Version]

p. 23 - change "Noise data" to "Noise parameters" in description

p. 24 - Version 1.0 examples should not have keywords

p. 25 - ordering vs. [Version], [Numbers of Ports] 

p. 26 - ensure bulleting

Bob added that the [End] keyword simply ends the file (remove "and any keyword 
or data blocks within it.") as unnecessary text.  [End] bookends the entire 
file, 
similar to IBIS.

On a separate subject, Bob observed that the options line contains scaling 
information, 
so it should appear before Begin Information/End Information.

John asked whether options was deprecated.  Michael responded that it was not, 
as 
scaling, data format and the network parameter type were specified by the 
options
line.

Currently, both [Version], [Number of Ports] have a fixed ordering.  Michael 
noted
that the current order is pretty good, as [Number of Ports] becomes an axis or
"stake in the ground" for placement of the other keywords.  Then, the options 
line
could be placed between [Version] and [Number of Ports]. Bob responded with 
support.

Bob asked why the [Reference] keyword was ordered the way it is.  Should not 
[Number 
of Frequencies] be earlier?  The overall team principle is that required 
keywords 
should appear as early in the file as possible.

Michael asked whether the team should mandate a given order for all keywords.  
Bob
responded that he would prefer not to do that.

Michael suggested moving [Reference] after the [Number of...] keywords.  This 
maintains the stated principle but is not intuitive.  Bob stated he would 
accept that.

Vladimir stated that the document should include two complete separate 
examples, with as many functions as possible.

Two more meetings will be needed to complete editing and changes.
