Presently there is a single central Hermes server at which informaiton
for users is stored. This server also provides an SMS gateway
for communication with Hermes users' and both wireless and wired
connectivity. Wireless connectivity is needed as there is a firewall
between wired and wireless networks, through which Java RMI callbacks
will not work.
