This must be why I had to delete Arial from my mac and replace it with
Arial from my Suse.

What about with OOO2 where fonts were available for OOO exclusively
http://wiki.services.openoffice.org/wiki/Font-FAQ#How_do_I_add_fonts_to_OpenOffice.org_2_exclusively

Fonts were installed in ~/.openoffice.org2/user/fonts/
So I was assuming that a font packaged in an odt file would be placed
somewhere similar on opening the odt file and then available exclusively
to LO when editing the document. This is where I used to place my custom
fonts and doesn't require admin access for font installation.
