Getting Startted with b4i

Hi!
I am thinkking to buy B4i with Machosted version but I have a few questions first:
1- I need the Apple Developer License since programming using debug
2- Can I use the application without a Mac so to debug my app can I use my phone like device without a license developer
3- What services can I do in Mac Hosted ?
4- I see the first installation and B4i-bridge, in this example the device is a real device or emulator ?

Thks.!
