Along the lines of simple socket-to-socket communication, netcat,
http://www.atstake.com/research/tools/network_utilities/ and netcat6,
http://www.deepspace6.net/projects/netcat6.html, its ipv6-extended
clone, might do the trick.

To my knowledge, both can read from stdin, so you can easily pipe
stuff to them, and they don't suffer from that same problem that
telnet does - disconnection upon encountering an EOF on standard
input.

Both also speak UDP and the old netcat can work as a server too,
which makes it quite useful as a monitoring proxy, so they both
qualify as must-have tools in any kind of ip-networked environment.

The equivalent of netcat/netcat6 that can be useful for multicast
testing is emcast, http://www.junglemonkey.net/emcast/, which is
actually a suite consisting of both a library and a trivial client,
that attempts to near what netcat should be if it spoke multicast.

Hope this helped,
