I reviewed some packets I just captured and it appears that there is a large amount of data that is being sent/received, but it all appears to be internal to the network and a good chunk is between my wife's work laptop and the receiver. I'll have to see if she has a media streamer enabled since at least one packet included UPNP or DLNA.
DIT: After a little more looking, YAMon has reported that the receiver is connecting to 22.214.171.124 on port 443 among other things. Since I haven't signed up for any service, I'm wondering why Onkyo is having the receiver connect to Google and what it's searching for.
