when running on two pc's only one instance is found on LAN. I think that adding a dropdown menu to gui for selecting the interface to bind to might allow it to get the mac address of that interface. Also is possible to add support for newer model emulation and add a webserver that works uses xhlhttp to do what libhdhomerun does, so that newer devices can be simulated too. If I set the device id to match part of the interface mac address, it is not found.
