I was just sitting here thinking when I had a GRAND idea, well with the recently released headset, I figured there would be someway to open up the voice input driver and output that through the system speakers, so basically a voice amplifier!
ALSO, Maybe even some way to not only ACTIVATE the drive, but perhaps store the ouput sound waves as data, It would probobly be RAW data, but that can be converted. SO perhaps a Voice recorder?
And MAYBE, just MAYBE, there could be someway just SOMEHOW to export sound through the IR port, like the new Ipod technology, maybe using sendRawdata() and then a raw encoder on the target PSP, which could then be voice chat!!!! Implementing Wifi from here could be easier with such things as a quick hosting and downloading sound file, which could then be auto erased after playback...
THis is simply speculation!
