i'm relatively new to the qubes environment. So far, i'm really excited. I just love the concept!
Anyhow, today i stubmled into a problem; using my chromecast from one of my vm's within in qubes.
As a network-technician, my first thought.. this cant be hard. Boy, was i wrong. After quite some reading, i'm still puzzled. I've noticed that the netwerking & firewall document has the status TODO. Maybe something i can lend a little help with?
I've read the following posts:

http://theinvisiblethings.blogspot.nl/2011/09/playing-with-qubes-networking-for-fun.html (is this still valid?).
I get the general concept.
- appVM's are connected to sys-firewall
- Sysfirewall is attached to sys-net
- no bridging involved, all routing.
But then:
- why are there subnets involved of 255.255.255.255?
- how much NATting is going on?
- what role does proxy arp play? Is it still used in 3.2?
Of course i can use wireshark and tcp dump to sort things out... but just maybe there is a good pointer to some other documentation?
Can anyone point out some more reading material? If any?
Cheers!
