Sure, if you run it in lower power mode, it would work for waking up in certain condition. But on few milliwatts power, it will not probably able to do counters or time measurement, or RS232.
I'm running 08M2 systems that are NOT in low-power mode, and measuring a couple of hundred microamps. Lets round it up to 1mA
At 5V, that's five milliwatts. In reality, it's taking less than that.
I built a temperature logger for a friend in the USA, but to be sure it was working I set it off here first (I was just sending him the code). I forgot about it, and found it later - still blinking it's LED every 15 seconds, still reading the DS18B20 probe, still logging... after 4 MONTHS - on the original set of 3 x AA cells. (They were not even fresh cells!)
At worst case, that's 2400mAh. 4 months is about 3000 hours. So even by those metrics, including running the temp sensor, it's WELL under 1mA.
Even in "low-power" mode, in all honesty I can't see a WC8 coming close to that.

We are thinking it might be worth to add a low power mode, so that only TTL input works, when certain condition met, it will jump up to full power mode to enable network.
This is still an interesting/useful idea.
I've lots of applications where I have WC8 either not connected to the world, or only intermittently connected (and even then, it is usually the WC8 that wants to initiate the connection so it could quite easily wake up first, then do stuff).
