I agree. I was trying to portrait the minimum overhead for the future,
where even MSIE has implemented conforming support for EOTL. If support
for EOT classic is not required in the future, then the EOTL as I
specified has only 8 byte overhead over plain OTF files.

OK. In that case, this practically the same as below.

I'd be interested about this, too.

Then I cannot see any cons with the EOTL format I suggested :-)
