Hi Rick - sorry about the delayed reply, I've been busy. I've had a
quick look at the thread and I've a few questions before I make any

Q1. Is there any functionality only one of your DHCP servers[*1] can
provide eg. wireless connection.

Q2. What is the maximum number of clients you are ever likely to have
connected to the networks serviced by these DHCP servers.

Q3. Do you use PXE/GPXE/RIS?

Q4. If either of these DHCP servers doesn't run Debian - what is/are the
make and model/s?

Q5. If either of these DHCP servers run FOSS - what is the DHCP package?

[*1] I noted your intention of having a backup/failover DHCP server -
I'd probably suggest a different way of doing that, but I'll wait on
some answers first.
