I am not a lawyer, as I stated before.  However, EOTL does not *allow*
you to ignore rootstrings, it *requires* you to.  You are *required*
to treat any data specified as 'padding' as meaningless and take no
action based on it.  Thus you're not bypassing any restrictions,
because any rootstrings embedded in the 'padding' area of an EOTL file
*are not rootstrings*, and they're required to be ignored.

(This is based on a hypothetical EOTL version which is based on an EOT
version that allows rootstrings.  The current EOTL proposal from
Daggett is based on a version of EOT which does not have rootstrings
at all.)

See above.  In the hypothetical EOTLwrip (with-rootstrings-in-padding)
format we're talking about, there are no rootstrings.  There is only
padding data which may be interpreted differently by certain legacy,
nonconforming browsers.

This doesn't seem to follow.

Indeed it won't.
