It's not just "advanced" things like camera access that browsers fail to replicate for the standard web platform. AFAIK no browser even correctly supports something as simple as non-"Normal" blending modes for SVG. And I'm saying this as a fairly staunch flash hater. A lot of these things we're supposed to be using to replace flash with HTML5 are simply not there reliably or sometimes even at all. SVG is a particularly glaring example of something which is woefully under-implemented.
