We're very aware of that! And we have tried to be careful around 
licensing issues.

That's not entirely true; the extended spec which the RabbitMQ server 
and official (and many unofficial) clients actually use:


is BSD-licensed.

However, I notice that the extended spec available from 
http://www.rabbitmq.com/protocol.html is only available in an 
AMQP-licensed version. Was that what you were talking about?

Anyway, we should correct that...

...but to know how high a priority to give producing such a spec I would 
need to know if any packages in Debian are currently using the 
AMQP-licensed extended XML spec. Can you tell me which packages these 
are? I can't get anything useful out of bugs.debian.org :-(
