There was something I was thinkin of trying. Since a wireless card tends to greatly shorten battery runtime, wouldn't it make sense to use something like diald to automatically bring down the wireless interface after, say a minut of no activity, then bring it up again when packets go out? Usually diald is used to control a modem, but I believe it can control any network device. The only problem is that it takes about 15 seconds for the wireless interface to initialize. But is there any way to put a wireless interface into a suspend mode, then have it communicate instantly when it comes out of suspend?
Has any one tried this yet? If not, I'll see about fiddling with this over the weekend, then post the results here.
