If there's a risk that John Doe could gain access to the NT and Unix 
systems where the sniffer software is running, then this does seem very 
unsafe. It would be better to run sniffer software on a machine that is not 
capable of supporting multiple users and doesn't support remote access.

Sniffer users that know what they are doing can learn a huge amount of 
information, including passwords, confidential data, etc. Both FTP and 
Telnet use unencrypted passwords. This may not seem like a big deal except 
that many people use that same password for access to confidential database 
files. In addition to passwords, the sniffer user is going to see realms of 
other data that could be confidential. (Once while teaching an onsite 
Sniffer class, I noticed that an executive for the company was printing a 
contract to sell the company.)

Running sniffer software on a shared machine is asking for trouble unless 
you are really sure a hacker isn't going to get into that machine.
