OpenDocument happens to do all object embedding by placing the object in 
a zip file along with several XML files that contain the markup for the 
document and the metadata, compressing the zip file, and the resulting 
file gets an .odf suffix. This is most often done for images and 
spreadsheets, but you can get any sort resource for the document in there.

You don't really have any guarantee that a word processor must modify 
the font to make it unusable. And your license doesn't say that must 
happen. And thus, when you say to a judge "this is not legitimate 
embedding", the judge will look at the words in your own license and see 
nothing to back you up.

Fonts embedded in HTML email are not modified. They appear as 
attachments, just like images, and you can pull them out.
