wifi : Adhoc using infrastructure mode possible with 3.XX?

[pspZorba]

I was able to code adhoc -game sharing and classic wifi infrastructure mode (with an acces point), but accordingly to this post, it should be possible to use true adhoc over infrastructure mode (Which makes sense).

Is there someone that was able to do that ?

was PspPet able to do that since he used kernel 1.5 and it is no more possible on 3.XX ?
