Dear Steve, Michael, Patrick and Mauro,

wow! Let me be the first to congratulate all of you on taking a bold, decisive step, which
I am sure with your combined talents can be successful. I agree that it is time to move on
from the multiproto era and work to create something to be proud of. Your alternative approach
sounds intriguing. I will take some time to try and understand your patch before commenting
any further.

Best regards,
Hans
