I start to agree that a continous stream when not necessary won´t help anyone...
But what about a selectable number of repeats of the last change before stopping to transmit a universe?

I worked with Enttec Datagate and had to see that these units didn´t work good with Pixelmad as well...

The problem is that I am in charge of specifying Catalyst equipment but when it comes to ArtNet node the lighting company will supply whatever they have in stock - and they will say Catalyst is the problem because our nodes work fine with Hippo and grandMAvideo...

It is then a really hard point to tell someone that the problem is in their nodes and not in my server...
