Sometimes - like when you have a cluster of machines - it is easier and faster
to write a command once and have it execute on all the machines. Expect is
really good for this since you can just feed it a list of machines and commands
and expect just goes and does its thing.

Don't you think it is much clearer to add a name to the default var? Like this:
my @servers = qw/ 10.10.10.1 10.10.10.2 /;
foreach my $server (@servers)
print "Spawning to $server\n";
$exp->spawn("ssh -l username $_") or warn "unable to spawn: $!";

I haven't tested all your code, but expect is notoriously difficult to use.
Matching the prompt and such exactly is a pain. Expect itself offers a little
bit easier debugging output sometimes too.
