As a test I did this:
pv -c -N One </dev/zero | nc -b 65536 host1 10001
but all I get is
^[[45;1R
on the sending end and
^[[63;1R
on the listening end. And there it hangs. Both ends. This is after I set up the terminal-type in Solaris. Cursor positioning? Why wouldn't it be interpreted properly?

Something Trevor said made me think of this:

Host 2:
(nc -l 10001 | pv -c -N one >/dev/null & nc -l 10002 | pv -c -N two >/dev/null & nc -l 10003 | pv -c -N three >/dev/null & nc -l 10004 | pv -c -N four >/dev/null)

Host 1:
( pv -c -N one </dev/zero | nc host2 10001 & pv -c -N two </dev/zero | nc host2 10002 & pv -c -N three </dev/zero | nc host2 10003 & pv -c -N four </dev/zero | nc host2 10004 )

As long as all the pv instances have the same controlling tty and process group, which is accomplished by putting the whole thing inside parentheses ( "(",")" ) the IPC stuff works correctly. It's designed for parts of a single pipeline yes, but this trick appears to fool pv adequately well.  At least on Linux and OpenBSD this works, not sure about Solaris.
