If you don't mind doing things all-manual, and all you want to change
is your NIC settings and a couple of controlled things, you can do it
all with normal ifupdown.  For example:

iface eth0 inet dhcp

iface net-home inet static
        address 18.101.2.59
        netmask 255.255.255.240
        broadcast 18.101.2.63
        gateway 18.101.2.49
        wireless_essid default
        dns-search mit.edu
        dns-nameservers 18.72.0.3

Then if I run 'ifup eth0', it tries to get DHCP; if I run 'ifup
eth0=net-home', it will bring itself up on the specified static
address, set the 802.11 ESSID, and specify some DNS parameters (using
the 'resolvconf' package in unstable).
