Thats an easy one....

Any generic system that receives time sensitive real-time information from 
numerous distributed nodes that must be processsed and relayed to
other processing stations *and* run the typical IP e-mail, ftp, httpd,
etc. packet services concurrently over the same pipes, as well as
network management traffic ad. infinitum.....

Running real time sensory data, for example that must arrive at remote
locations within a few milliseconds on a packet switched network,
for example.... I'll attach a few references for those who don't wish nor
have the time to pull down the 12 page postscript draft mentioned
earlier...
