I have posted an updated version of the Decision Tree:

Yes, I let my prejudice slip in there :).  I have added some notes to
the newest version for the 'IPv4 only' path on the top right and the
'not IPv4 or IPv6' path on the top left.  They instruct the user to
skip the v6 questions or replace v6 with whatever other solution is
decided upon, respectively.

Great suggestion, thank you.  I have modified the drawing to reflect it.

I used Visio 2003 - I know that Visio has many compatibility issues
but I am more than willing to make it available.  Is there a better
format that more folks could work with (.vdx, .svg, .dwg, etc)?  Or
should I just post the .vsd?  I think it would be great to have some
printouts of the final version available at the meeting (but I think
my kids are great too ;)).

Agreed, I made this change in the updated the diagram.

Agreed and done.

Thank you!
