The use cases go beyond "proof of concept", especially since you can put the WLAN device in promiscuous mode. It would be interesting to watch all the potentially malicious traffic on your wireless LAN directly from your N900.
I'm not sure if snort works on wireless.
Anyway it is resource hungry program so it will kill your battery quickly.
I thing OSsec would be nice but for different purpose like monitoring and defending your phone (via active response, should be possible since titans kernel have iptables)

Any ideas are welcome.
