The message below didn't go out to CodherPlunks earlier because the list
was hosed for a few hours. So I'm *forwarding* it now.
(Thanks to Hugh Daniel for fixing the problem with the list.)

Some of us have been burned in the past and don't want to be burned
again.

So you are saying that the intent is, in fact, that novel modes and
uses would be okay without license or payment -- whether mentioned in
the FIPS or not?
You do realize that this partially contradicts your previous statement

I would suggest that if you want to make people non-nervous, that you
make sure that you have one, and only one, statement out, which
completely clarifies your intent and is airtight.
