I believe this is what I was talking about - static DHCP.
However, it only allows one IP address per name and one MAC address
per name.

True - but I would like the backups to 'just' work whether using the
wired or wireless ports. For now, I have the static assignment set for
the wireless NIC since that is what people used most... but sometimes
you actually prefer to use the wired NIC, especially for backup, since
the link speed is faster.

I will look into this. I'm not very familiar with nmbd/smbd except for
use with Samba - but not with name resolution...

Good thought - exactly what I detailed in my other follow up email.

Interesting thought but probably overkill, especially since the
laptops are pretty slow...
