You use network rendering in the batch queue. So yes you can still work. The licensing on grid was expanded, but I believe it is per thread. Whereas just C can be run on a machine w/ many threads, i.e. 8 cores. That's before using rendering nodes. Cpro comes w/ extra rendering node licenses. So you might not need grid. There are some bugs w/ it I believe, not sure whether they were fixed. It is important to know the licenses are per thread. It was updated I think so maybe it is fixed. They do have a 30 day guarantee. If you have Pro you can put anything in batch queue and still continue working w/ no network rendering.

No need to think outside the box....
