multiple thin client servers

[Gavin McCullagh]

Hi,

has any work been done or is there any documentation on how best to deploy
multiple thin client servers.  I'm thinking in terms of if you have need
for several thin client servers how you would:

1. Make sure home dirs, authentication, etc. work across both servers.
	- nfs share home dirs?
	- nis for auth? ldap? 

2. If either server went down, the other could continue to function in its
   stead.
	- clustered dhcp/dns server?
	- nis master/slave? ldap?
	- mirrored home dirs (ie not nfs)?

Is this sort of thing on the roadmap for Edubuntu?  I'm sure any given
sysadmin can come up with a home-brew way to achieve most of this but it
would be nice if Edubuntu had guidelines on it and perhaps designed the
overall system to ease setup.  I believe ldap is in the pipeline which is
probably a useful part of this.

Does anyone already do this?  Are there any such docs?  Is this a crazy
thing to try to do?
