That is very much not true.  Maybe if you had all your scripts installed
in NFS, then it'd have to pull the script off NFS, but it'd have to do
that for NPRE or checy_by_ssh.  check_by_ssh merely ssh's to the box,
runs the command you specified *on the remote box* (meaning it runs a
binary that was already on the remote box), then does some tricks to
make sure the exit codes are right.  That's all.  It doesn't have to
push the script over or anything silly like that.
