Not very legal.  There is something in the license agreement about prohibiting
people from reverse-engineering the protocol.  Also, technically, it would be VERY
difficult to do with multicast UDP packets...that dosen't mean it wouldn't be fun
to try :-)  I might just bust out the sniffer after finals are over...

Stevens, UNIX Network Programming Volume 1.  Prentice-Hall.  1998.  I count it as
one of the most valuable and informative computer books I own (the first edition
came out in 1990 and was the one true UNIX geek book for network programming.  The
new release is being totally updated and broken out into three volumes).  Rollins
should have it at both locations, and if they don't, Ian will order it for you.
