Cloud & Swarm Rendering

I just managed to install swarm and render over two computer simultaneously, wonderful =) Now i have following questions:

1. Do i have to be in the same network to use swarm ?
2. Is there any possibility to render from home by using the swarm power of the computers in my office ?
3. Is the Cloud rendering beta service already open and how can i use it ?

thank for your help in advance !
kind regards

1. Do I have to be in the same network to use swarm? - Not necessarily, but there should be working routing between the networks and the master node should be set manually - V-Ray Swarm
2. Is there any possibility to render from home by using the swarm power of the computers in my office? - Well - if you have a VPN set up and also a very fast connection over it - yes. In practical terms - I hardly doubt it’ll work OK. It seems to me that it’ll be a lot easier if you just connect to an office computer remotely and submit render jobs from it.
3. Is the Cloud rendering beta service already open and how can I use it? Not yet, you can apply here and you’ll receive an e-mail when it’s publicly available - Chaos Cloud – Present, review, and render — easily perform every step on the cloud | Chaos
