Greetings:
Thanks for the clarification, Paul, that's very exciting news. Any
idea when all of this magic will start to come together ? Is aes in the
planning stage or is prototype working now ? And does this news mean
that you're back to work on Quasimodo too ?
And do you ever sleep ?! ;)
Best regards,
