Just a 2p thought:

My suggestion would be to use DHCP with MAC-based reservations.  

Isn't it right that any wannebe hacksor can easily spoof his/her
mac-address to let it look like an "authorised" one? And wouldn't this
mean that the only barrier to get an IP is to choose/find a correct
mac-address, which might be done by sniffing the network or something
alike? If so, giving away Ips based on mac-addresses doesn't look too
secure to me, does it?

Exactly. Using DHCP this way helps you with administration, but is not
a security measure. It just gets you a little bit better security than
not having DHCP and thus no real control on who has which address.
