When using Devicescape to share personal WiFi networks it removes the need to divulge your WEP or WPA encryption key to your 'buddy'. Devicescape automatically deals with the security, provided you share the network details with your buddy in advance (i.e. when they are online elsewhere) so their account updates with your networks details.
I've now installed Devicescape on several wireless PCS and my Nokia E65. Works perfectly so far.
