I have just released a new version of Net::OpenSSH::Parallel supporting the rsync functionality available from Net::OpenSSH.

That would allow to maintain a library of perl modules and scripts replicated across all your servers, though it needs the rsync binary installed on them!

use Net::OpenSSH::Parallel;

my $p = Net::OpenSSH::Parallel->new;
$p->add_host($_) for @hosts;
$p->push('*', 'rsync_put',
              { recurse => 1 },
              '/my/local/perl/library', '/tmp/my-perl');
$p->push('*', 'command',
              { stdout_file => '%HOST.out',
                stderr_file => '%HOST.err' },
              '/usr/bin/perl -I/tmp/my-perl/lib /tmp/my-perl/script.pl
+');
$p->run or die "something failed!"
