Are there any devices on the market which properly support PSM in
Ad-Hoc mode? At least N800/N810 don't support it. 

I have heard that the standard is quite unclear regarding this. And,
after seeing the countless ways APs have managed to break PSM in
infrastructure mode, I can only imagine what kind of interoperability
problems there are with PSM in Ad-Hoc mode :)

So I think we should forget PSM in Ad-Hoc mode, at least for now.
