Basically as the title says. Wlan traffic meter. Does anyone know of a small app or widget or command for this. I see the command posted above but that isn't much use as it is only from last power off/reboot.
Could anyone make an app/widget for this. I don't know the first thing about devel. I'm pretty sure it wouldn't be too difficult if you know what you're doing, but maybe I'm wrong. I would be very grateful to anyone who would make something like this. Can anyone help?

NB: This is a request for wlan not gprs data. I have already got dataplan monitor.
