It is also VERY dangerous on the LocalTalk side: you can peek
username/password for accounts on remote hosts (using NCSA Telnet), but
you can also peek username/password for AppleShare volumes (but not for
TOPS which seems to use password encryption). You can also grab whole
Postscript files sent by someone to a LaserWriter, without anyone knowing
anything (care of examination subjects). The only workaround I can see
is to have separate subnets for Macs containing "classified" informations.

You can also use subnets: username/password pairs are only available
on the subnet(s) from/to where you are login in.

It is freely available from Cayman...

It is so easy to use it...

This last suggestion maybe a good thing for "honest" pirates. I think
that the only good solution is to use separate networks for Macs (and
LaserWriters) containing "classified" informations.
