You should have asked licensing <at> mysql.com not the list. And internals
is also a bad place to ask but this got forwarded.

No, If you want to distribute the MySQL server or client with a closed
source application you will need a commercial license. 

That is the income that pays for all the MySQL developers!

I checked this out and you are right !!

I think that we could add an entry into our WorkLog to enable inserts
from the same table when SQL_BUFFER_RESULT is used.

Peter sent me a note saying that the docs are wrong and that
SQL_BUFFER_RESULT is more limited than that. I hope you're right!

Yeah, exactly.  If MySQL can reliably detect that, it'd be ideal if it
"just works" when someone tries it.
