I live in CT. My grandchildren live in Indiana and NY. Is it possible using E-Z APP and FaceTime or something similar for my grandchildren to see my train layout and talk with me while they control the DCC trains from their home?  I know EZ APP uses Blue Tooth and is limited to a 100 feet range.  Looking for creative solutions.

I have used my IPhone with Face Time for them to watch the trains but it would be great if they could control the operation remotely.  There must be other grandparents wanting a similar solution.  Thanks.
