I think that is the first reason they implemented the ethernet connection on the VIP receivers but, like you, I'm concerned about the audit people so don't plan on disconnecting the phone lines. I do like the caller ID so may leave the phones lines connected anyway.So is anyone for sure that DISH will allow just a broadband connection ONLY? I wouldn't want the audit nazis calling if I did this and disconnected the phone lines.
I successfully completed a test on both 622s using one SMC ethernet wireless bridge and the built-in broadcomm. Works but seemed very slow uploading logs from both receivers.
