Something to be careful of is that while UDP is fast, it is not secure. You can lose packets and there is no way for the sender or receiver to know it was lost. Because UDP doesn't have a "connection" like TCP does, the sender doesn't know if the data is going anywhere and the receivers have no way of knowing if anything is being sent. Picture a radio station. A guy working the night shift hopes there is someone somewhere listening to his broadcast, but he doesn't know. Likewise, if you turn on a radio and hear nothing but static, you may be listening to a frequency where there are no stations broadcasting, or the station transmitter might be off the air, or there might be interference keeping you from hearing the signal, but again you don't know which.Mike...
