Edubuntu with two servers

[Asmo Koskinen]

My next stop will be Edubuntu Classroom Server -edition with 2 servers.

I got now working environment with 2 servers and 113 t5135 -thin clients 
at a school, I use dhcpd load balancing (Ubuntu 6.06.1 and LTSP 4.2):

How hard it will be with Edubuntu Classroom Server?
Do I need change anything more than dhcpd-conf files at master and slave?
Can LDM handle 2 servers?

I do not use LDAP, just copied passwd-files in both servers, /home is 
behind nfs-server (third server).

I found this line:

"Add support for multiple application servers to ldm Make it possibler 
for the user to select from a list of application servers to log in to"

So this feature is on the road, but not yet here?
