OK, I tested some sample projects and everything worked just like if I was compiling locally in my LAN.
I did also some test-project with some images to test transfer-rate and there were no problems at all.
Everything is very transparent - you hardly notice the small delay there might be when sending / retrieving data with remote-server.
Seems like a powerful and fast server which I guess will be important if many users connect at same time.
One thing I noted though:
-if WIFI gets disconnected and you loose your connection with B4A-Bridge, B4A does not detect this immediately. I compiled an app, data was sent to remote-server, then I received "Installing file to device", next "Installing with B4A-Bridge" and finally "Completed successfully". Of course, nothing was installed on my device.
One thing I didn't like: as soon as "Completed successfully" appeared, its windows was iconized. I prefer to see this windows after comnpilation. If I don't want it, it is enough I compile in background.
