John, I still use Homeseer for things that aren't incorporated in MainLobby today.
Tom Caldwell's Shopping script w/ bar code integration
Local Movies / Theater showing
A few more things that aren't coming to mind.
It's all working super reliably and it's all fun. Why change?
True, I have moved most to MLServer 3, but that's what I need to do to test MainLobby 3 suite. Real world testing.
The nice thing is there aren't too many things I can think of that aren't possible with MainLobby and Homeseer, especially in combo.
