Thanks for addressing this, guys. Their are 2 "zones". They are both surround setups. One is a 6.1 Atlantic Tech based and the other will be a 5.1 KEF motorized in-ceilings that we will install. Both have their own A/V rcvrs. The 6.1 is being driven by a an existing Onkyo. The second will be driven by a Marantz SR7500. The 7500 will probably also drive stereo on the balcony. As for the touchpanel, it needs to be able to manipulate playlists, veiw DVD's in storage (I need covers!), and view the 4 cameras. The cameras are all analog (as oppose to IP). Both theaters will have their own remotes (most likely MX3000's with TripleB software to show the DVD collection, another new level of programming for me) and I will most likely run cable for IR. Entire job is retrofit. iPORT will be a local source and hence, feedback doesn't matter. I will absolutely need a GUI via both theaters displays. Hope this helps clarify. I am not dealer direct with ELAN, open distribution?
