Wireless : best policy / pratice to start it

[Bruno Costacurta <cob1@biz.tiscali.be>]

Hello,

I'm looking for the best policies / practices to start wireless networking.
Briefly I use wireless in following locations:

-home:
wpa via wpa_supplicant

-public (bars..etc..):
no wep/wpa

Both works fine. Currently I start a console logged with user root to call 
ifup with related params.
Should I used root to call ifup ?
I would like to keep a manual connection as I do not want to automatically 
connect.

Hereafter my partial file 'interface'

(snip)
# wireless public places
iface public inet dhcp
        wireless-essid any
        wireless-key off

# wireless at home using wpa
iface homewpa inet static
        wpa_driver wext
        wpa-conf /home/bruno/.wpa/wpa_supplicant.conf
        address 192.168.1.4	
        netmask 255.255.255.0
        gateway 192.168.1.1

Bye,
