How many websites can we embed at the same time and please elaborate, can we integrate 10 calenders at the same time and 10 people will manage the booking etc separately.

Can we also have the option if a booking is booked one website A, the calendar 1 will be manage this bookings and notified the Calendar 1 user only?

and if the booking is booked on website B, calendar 2 will only managing this bookings?
