I just started playing with a T3-Vz and XP-8 in my house, and the integration with my Onkyo receiver is great. The volume feedback and tracking is working great (I didn't use the popup since T3-V screen is large enough to show volume graph all the time). Reconnect time is between 1 and 3 seconds as Andy says above.
At first I was having problems as the control and feedback from the receiver would stop working after a few button presses on the remote. I realized soon after that I had both the Onkyo and GrafikEye drivers assigned to the same port (Port 1), even though I wasn't using the GrafikEye commands yet. The XP-8 must have tried to assign both drivers to the same port and they were stepping on each other. Once I assigned the GrafikEye driver to Port 2, all was well and rock solid.
So far so good, and I've even got my Linksys wireless router within 4 feet of the ZM-24. Next is to add more features and integrate my GrafikEye controller.
