Well, the bridge assumes that both you and the computer are on the same network.
So, you spool up a VPN on your computer, but you would THEN have to also spool up a VPN on the phone for this to work.
I do in a number of cases using a VPN on my phone. I'm lucky, since the one case is the company uses forte-client. And there is one for android.
So, if you have a compatible VPN client for the phone, then this could certainly work. I would think it going to be somewhat "slow", but it certainly a possible.
and I suppose you could use the emulator on that remote machine. And for "some" tests? Well, then just email the apk result to the phone - assuming that developer mode (and allow of installs is turned on), then you could transfer the application to the phone for some tests. But a VPN will work - the phone will thus just have to be attached to the same network that B4A is running on. All in all? I think getting B4A up and running on your computer would be the best approach here.
