Subject Re: Artemis deployment question
Date Fri, 16 Oct 2015 14:19:06 GMT
You could have the Bridge listening to one subscription for one node..
and sending to the other center... so everything received in one place
would be send towards the other center.


If you have producers on the other center though things will be
complicated..as you would send back what you received and you would by
math definition feedback messages on an infinite loop. Just be careful
with that part. (you could filter out feedback with an expression
though).

It's a bit non orthodox but it would work.
