I don't own any Apple gear, but sceneview requires Java, so I guess no. There is the websceneview. It only requires HTML as far as I know, but it's programmed different from the Java based Sceneview.
I don't know IHC Remote, but if you can't specify the port I guess you will have to ask your ISP for 2 public IP's. One for each controller.
Again I don't know IHC Remote, but the build in calendar in LK IHC s.... big time. For Scheduling I would look for the Visility board, IHC Captain, OpenHab, Domoticz, or one of the other third party products, which have reengineered the LK IHC API.
I think there is a thread about this issue somewhere here on this board. I can't recall if the latest firmware for the HW 6.1 controller have a fix for the Android phones, or you need to upgrade the app.
