Had a little play this morning.
Lanspy with it's default options.
Laptop1 using wireless with ZA, no sharing and no response to ICMP Echo.
Laptop2 using wireless with Windows firewall , no sharing and no
response to ICMP Echo.

Lanspy does not see either laptop.

If I allow sharing or ICMP Echo on either Laptop then Lanspy will see them.

If I change Lanspy's options to not check "Ping" then it will detect the
MAC addresses of both laptops even if they do not allow sharing or do
not respond to ping. However if the laptops are locked down it takes
forever to do a complete scan of all the checks that Lanspy can carry
out and it is best just to check for MAC addresses if you are checking
to see if anyone is piggybacking onto you network.
Shame it doesn't seem to have an option for continuous scanning.
