"something" != "a transport"
TCP would be the desired transport:

$ grep rsync /etc/services
rsync           873/tcp                         # rsync
rsync           873/udp

I would have brought up netcat, as Scott did, if it had some form of
integrated integrity check.

#include "helping.h"
if (!helping())
	meet(pot, kettle);
else
	information.flags |= USEFUL;

helping.h:
#define helping() is_grokking(user)

Semantics...
I intentionally avoided the above point for brevity.

_I_ can find it, but you knew that...

Did anybody mention that the network segment is _not_ private?
