I think epub shall be made with one font - otherwise it will be too big if fonts are embedded. So your interface with one font embedding seams quite reasonableas for me. Just make this checkbox active and embedd the font selected in the box.
To protect fonts copyrights, you can allow to export only free fonts, such as DejaVu and other fonts developed by FontForge - they are included anyway into OO package.
