Does the B4A-Bridge app allow ADB communication over a network (instead of USB)?
If so, then if you know the IP address of a remote android device, you could theoretically control it over the internet, so you can offer "Remote Support" to users.
That would come in handy when my grandmother calls me up and says the "The screen changes when I press this button", and my normal response would be "What screen grandma....what button are you pressing grandma?"
