If the request was for off-site www information, a proxy running on an NCF computer could relay the request. Note that this allows NCF to limit the Internet bandwidth used by users surfing, allows for the possibility of a cache, and also allows NCF to limit what servers are accessible, possibly on a per-user basis.
Telnet would require a proxy as well, and this proxy would be as expensive
in CPU terms as a user logging in and heading out again with telnet.
It is hoped that many of the information sources available only by
telnet will get WWW equivalents in the future.
