I'm with you on the security concern.  One for the kids, one for the 
adults.  That's especially so, given that the adults are presumably 
conducting B & G Club business on the staff server.  At a minimum, 
they're probably doing some online banking or buying stuff online.

Remember that the biggest considerations for LTSP servers are as follows:

1.)  sufficient DRAM,
2.)  sufficient network bandwidth, and
3.)  plenty of CPU.  Multiple cores are a major plus here.

You don't need a fancy "server grade" box for this.  Both Intel and AMD 
make monster quad-core chips now, with Intel somewhat in the speed 
lead.  DRAM is cheap, and copper Gig-E is cheap.  Just build a couple of 
boxes w/ 4GB DRAM each, thus realizing yet further savings *and* knowing 
that you picked good hardware.
