One suggestion about how to add the Electronic EULA Abstract (EEULAA) to fonts is to create a new OpenType table with standard fields. Fontlab has created an online application which creates such a table and inserts it into a font and reads such tables from fonts. Here is the table description:
The table contains the principal positions of the EEULA abstract in simplified (machine readable) form. Each position of the EEULA abstract is represented by an identifier, bit value, numeric value and optional text (Unicode).
This table specification is in “beta” version and is given here only for reference. A more up to date version is kept as a Google doc
