That's interesting about the power levels per-channel. In my case, I actually WANT the not-going-through-walls experience. In an apartment (or hotel room), the goal is just to get as much coverage as you need, not to blanket three floors down. Smarter power level selection on APs (specifically consumer grade) would be nice. If all of your clients have acceptable signal strength, ratchet down, otherwise try ratching up, etc. If nothing else, it would be nice if manual control was possible (e.g. Apple removed transmit power selector from AirPort Utility). There's also the problem I mentioned with OS X (and possibly other clients) being biased towards 2.4GHz. I have to create separate SSIDs for 2.4 and 5 GHz at home, and some devices live on one and some on the other. Otherwise, I'll see occasional periods of really terrible performance with 2.4GHz, presumably because of interference (I can see 20+ SSIDs from my living room).
