Correct, you only need to tag a kernel for tftp-distribution and a 
network mountpoint. But I guess for the voicemail system and gsm files 
it would be nice to have some sort of cache. And for the complete system 
a serperate network interface for 'harddisk' traffic would be adviseble.

By a 'server register procedure' it would be possible to dynamically 
allocate specific servers to specific task. But what should be done with 
IAX tunnels or physical links to the network? What if a server fails? 
The total system must check such things and make an other system fail 
over (hard- and software).

Making a 1:1 mirror should provide you the same, my opinion (and 
ofcourse totally not valid): why place two servers to use only one 
server? Waste of money. So make the second system a offloading system 
with a VRRP-ip setting of some kind so that the system does fail over in 
case of power failure. This probably imply if server 1 has a E1 link, 
you need to have the same for server 2.
