I found this very cool app for Android called IP Webcam

https://market.android.com/details?id=com.pas.webcam&hl=en

What this app does (among other things) is allow you to capture images directly from the camera on an android tablet or phone over wifi via a simple URL.

So if your android tablet/phone is connected to your wifi as ip 192.168.1.2 the IP Webcam app will give you various URL's to grab pictures with:
Simple frame grab - http://192.168.1.2:8080/shot.jpg
Full resolution photo capture - http://192.168.1.2:8080/photo.jpg
Full resolution photo capture with autofocus - http://192.168.1.2:8080/photoaf.jpg

As you can imagine, this is super easy to integrate directly into a VFP app.

The IP Webcam application even supports running in the background which leads into the really cool part. You can use an application like Splash Desktop to remotely access a computer on your network which is running your VFP application. And now your VFP application can capture images directly from the Android device's camera!

Now I'm trying to find an equivalent app over on the iOS side, but I'm not having any luck. Anybody come across something that offers similar functionality?
