In summary, I ask for your advice on two questions.
Q1: How do I embed a TT font into PowerPoint 2007 for others to edit, and,
Q2: What is this "css" legal stuff and I do I comply with it in PPT 2007?

This is not a question for clueless clods such as Goodguy, Lewis, & nospam.

To clarify the font issue for non-commercial use in road signs,
much has been written about the subject of choosing roadsign fonts:
http://www.nytimes.com/2007/08/12/ma...12fonts-t.html

The current standard USA sign font is (still) Gothic:

More than a decade ago the choice was either Gothic or Clearview:

Where Clearview began to be phased in around 2002:

However Clearview was discontinued due to issues:

Today, the best public font for road signs is:
https://store.typenetwork.com/foundr...ies/interstate

However, that font is not a free font; but legally free fonts exist.

Specifically I have chosen the free "Roadgeek 2005 Series B" narrow font:

Download the desired free font ("Roadside Series B Regular") he

Determine the license agreement, where the license says:
"This font may be freely distributed and used provided copyright
notifications remain intact."

The copyright notification says:
"Copyright (c) Michael D. Adams, 2005. All rights reserved."

Look up how to embed the fonts into Windows PowerPoint 2007:
https://support.microsoft.com/en-us/...-in-powerpoint

Check for compatibility issues with Mac PowerPoint 2007:
http://www.pptfaq.com/FAQ00076_Embedding_fonts.htm

The line of interest on embedding compatibility in that summary is:
"Mac versions of PowerPoint can't embed fonts or use fonts that have been
embedded by a Windows version of PowerPoint."

The line of interest in the copyright notice is:
"This font may be freely distributed and used provided copyright
notifications remain intact"

The questions, as stated in the original post, are only about:
Q1: Embedding a specific font into both Mac & Windows PowerPoint 2007.
Q2: Complying with the legal agreement that the copyright remain intact.
