You may freely distribute TEXFonts provided that:
You must not distribute programs that modify TEXFonts in any way except to add font packages to the 3rdParty directory. If you need TEXFonts to be changed for some reason, please ask 2.
You may not change TEXFonts but you can distribute font packages as separate items, provided that your installation system (program or instructions to the user) installs the package in the 3rdParty directory (you may create sub-directories in the 3rdParty directory).
