I've tested with two different AP :
-Freebox v5 (ISP DSL modem + wifi AP), which is based on ralink 2661
(802.11g + MIMO, pre-n)
-Linksys WRV54G

both with timeout 200ms and everything seems to work nicely. I didn't
notice any slowdown.

The only "problem" is to test extended battery usage ;) Since it is only
triggered by timeout on network activity, autonomy can only be gained
(and therefore mesured) this way for interactive usage (web browsing,
IM) and not by stressing network (for instance, by playing a radio

I guess it will be hard to find a good testcase to show how much power
is gained this way.
