Subject Re: [Discuss] Chronicle Queue transport for Aries rsa (licensing)
Date Fri, 25 Mar 2016 08:07:51 GMT
Hi Christian,

it's what I said in my other e-mail: we should wait that Chronicle fully 
switches to Apache (and not dual license).

If they already plan to go to Apache license, IMHO, it doesn't make 
sense to use another cat B license: they just have to go to Apache 
license if they agree with.
