It isn't, and I fail to see how that could work at all.
check_icmp and ping alike mark their packets with pid, sequence-number,
host-id (decided internally) etc, etc. Modifying the ip->src_addr field
would cause the targeted host to send its ICMP_ECHO_REPLY packets to a
different host, so check_icmp (or ping) wouldn't be able to pick them
up at a later time.
Otoh, it's not hard to implement, so convince me it's needed and I'll
add it :-)

That's rather ancient, I think, although I don't exactly follow the
nagiosplug upstream development that closely anymore.
