I think the problem is, that you are doing an OR condition (which is always true in your case) when it should be AND. You should try {parm != 0 parm != 3}

Have you tried to render it. in my experience those little display artifacts just go away in the render.

It's just like normal remote network rendering.

mantra -H host1,host2

It's important to not have spaces in between the hostnames and the commas.

It's certainly useful but I found that it has problems with refreshing automatically.
