If you want to ask a question of the Apache OpenOffice project you can send it to: email@example.com
That's where we do business, openly and transparently on publicly-archived mailing lists. We don't resolve issues behind pay-walls.
As for cooperation, we (IBM) have reached out to the companies who do the vast majority of the LibreOffice coding, and offered to help them with the Symphony code, especially in the areas of accessibility and Microsoft interoperability. They said they were not interested.
So I suggest we try to leave hypothetically behind, and if anyone who actually has the ability and desire to do something with this code has a genuine question, then they can take to the Apache mailing list. But hypothetical from bystanders are not really interesting to me.
