I don't believe it's possible for UDP *not* to be installed if you're
using TCP/IP networking. Both DNS and NetBIOS require UDP.
UDP is extremely useful for specialised purposes, mainly broadcasting.
I've also used it as a wakeup signaller.
It isn't suitable for use with a stream or a connection-based design,
but low-level support is definitely needed.
