Agreed...build it & I'll buy it!
I do an internet radio/video show & would use it out in the field as a reporter.
Just as a side note, though, at this time, you can semi-accomplish that using QIK.com, and yes, even using T-Mobile (tho it is slower then malassas!) . The other down side tho is the fact that you cannot see the screen. Agreed, having a cam on the front would be perfect.
Likewise, just having the ability to use a Blackberry as a webcam while connected to the laptop would be great!
