If you use a dual NIC setup on your K12LTSP server it shouldn't matter  
that there are different subnets. Just make sure you attach the switch  
for your thin clients to the NIC that does the DHCP for LTSP and that  
you connect the other NIC to the school network for internet access.  
If you do it the other way around things won't work and you'll be  
running a second DHCP on the subnet, which other machines (and people)  
are not going to like.
