configuration suggestions and browser lockdowns

[Bill Moseley]

Our small elementary school received a donation of reasonably new
machines, all fast P4s with 1GB and large disks.  One common use is
educational games via flash over the Internet.  Although much of the
documentation discusses using LTSP, my thinking is that there will be
quite a bit of screen bandwidth needed.  Since the machines are
powerful I'm thinking it makes more sense to not use LTSP.

This does make management a bit more difficult, though, especially
if the school decides to give out logins for each student using the
machines (instead of, say, a "guest" login).

Can anyone offer suggestions how to best setup this configuration.
Seems like NFS mounting /home, but I'm wondering what else can be
shared to ease management.

Another question is how to lock down the machines.  I've looked at the
Lockdown Editor Pessulus and Sabayon.  What about blocking URLs?  Mac
OSX/Safari has a reasonably easy parenteral control where the browser
won't go to any domain that isn't defined.  And when it's attempted
the admin can enter their password to provide access.  Any pointers
how to implement this?

Thanks very much,
