Not sure if people are aware, but to use as a webcam in Windows with Skype:

• start streaming through VLC
• start a Skype call (voice only, as you won't be able to do video without webcam hardware installed)
• select "share desktop" option
• select "share specific window"
• select your VLC window that's streaming from your N900

Obvious issue is still the lack of sound, and even if it was integrated into PhoneStreamer, I don't know if the share desktop function of Skype also sends sound.

Any chance to have audio processed in the future? Preferably by a wired headset, as the microphone would be in a better position.
