I've come back to this now, and tried N:O:P. It makes it very simple, here's the core of the script: 
for my $host (@hosts) {
    $pssh->add_host($host, user => $user);
}

$pssh->push('*', 'command', { stderr_to_stdout => 1 }, $cmd );
$pssh->run;

My next problem is that I want to decorate the return from each host, to tell them apart. Perhaps something like this: 

%) net.pl -c uptime kermit fozzy
kermit)  10:49:37 up 3 days, 21:38,  0 users,  load average: 1.00, 1.0
+1, 1.05
fozzy)   10:49:37 up 6 days, 21:08,  0 users,  load average: 1.00, 1.0
+1, 1.05

I'm not sure how I would extend N:O:P to do this. Probably have to go back into N:O.

See my OP for an update, as I had a D'oh moment, and realized it was that easy.
