I thought someone had done it long ago with k12ltsp, but I haven't kept 
up with newer versions and don't have anything installed myself now. 
The only tricky part should be arranging load balancing/failover for the 
dhcp and boot service if you have more than one ltsp server.  If you 
don't care about failover, you could just feed separate sets of clients 
from the 2nd NIC of each ltsp server.  You might be able to make a 
home/auth server out of ClearOS without too much trouble since it uses 
LDAP natively and it would be easy to add email and web services (etc.) 
managed with its web interface.
