Is this the Hughes DirecPC system? Or is it the CanCom one?
In either case it is a network connection and it makes you vulnerable.
Your are relying on Hughes' or Cancom's firewall (if any) to protect you
unless you block off the admin machines at that school from the teaching
machines with an internal firewall. I've helped set up those systems at
a trade show and even the technical people didn't really understand what
they were doing with it so I wouldn't trust anything they say without
actually testing it myself.
I don't know how far this remote school is from the nearest other school
but if it's within 25 miles or so you really should consider a wireless
system like the ones that http://www.wi-lan.com has set up in Medicine
Hat. With the right towers and antennas and topography this may work and
you then control the link and can secure it with encrytption.
