This is basically wrong.  TCP sockets are easier to implement for
almost all applications, precicely because they are reliable.  UDP
will only look easier if you plan on skipping the code to recover from
a lost packet.  Some applications can do this, but the property tree
can't -- property access is non-idempotent in the general case.
Listeners can have side effects.

I'm not sure what you mean about "less distinct in destination", both
TCP connections and UDP packets must go to a specific destination
address (although you can use UDP to a broadcast address on
your local LAN).
