Well, sure, you can use an ODF package just like a Zip archive and add parts to
it.
The ODF Specification does not prevent that.
However, the META-INF/manifest.xml file should be updated to include the
addition.
You can't count on any ODF consumer preserving a file that seems to have no
use, even though there are those who think such accretions should be preserved.
People who worry about document security, authenticity, and corporate
information leaks tend to disagree and arrange to have their implementations
delete material that is not recognized. There are implications for
digitally-signed documents, as well.
The problem with this is that now someone has to fish the fonts out of there
and install them where they are actually recognized for presenting the
document. If LibreOffice is updated to automate the capture of fonts and their
extraction again, aren't we back to the previously-unsolved problem?
I don't know. Is this what has happened to the .pdf files? Why could not
ODF use some form of embedded fonts as Adobe Acrobat does now? There
doesn't seem to be a problem with this.
At that point, it might be better to do it the other way round. Put the ODF
document in a Zip archive (or tar.gz or whatever) along with the fonts and
instructions on what to do with the fonts if one wants a rendition of the ODF
document close to what was intended by its author.
Or just separate the fonts into a handy Zip bundle that is available somewhere
and perhaps put a little note in the document about what fonts work best along
with information on finding and installing the font package. Observing the
necessities of license conditions, of course.
I am sure there are covert arrangements that could be created. I have nothing
to say about that.
Doing this at the user level is too complicated. It would have to be
done seamlessly and unseen by the user for them to consider the use of
ODF files worth using.

Hi.
Can the ODF file format not include a container for user-data. May be
specifying how that data should be catalogued but not what that data is.
There is no worry about legalities in regards ODF and placing fonts in
that data. Then LO would be free to place fonts in that "user-data" and
use them as required for faithfull document transferal. Provides a
solution while the debate continues.
