Hi, Jonathan-

Webcam input is indeed an interesting subject, but not SVG-specific...
it's better explored in the WebAPI WG (where there was some talk a while
back, at a F2F); multi-pointers (a la the Wii) also belongs there.

As you may be aware, there is a lot of activity regarding video in W3C
recently, including the recent Video on the Web Workshop [1].  I don't
recall webcams being discussed explicitly there, but it is something
that should be addressed as part of the same set of activities.

Of course, SVG and HTML5 each have <video> elements, but those are for
"output", not input.  I would expect video "input" to be handled in a 
dedicated
DOM-related spec (with a dependency on the Progress Events 1.0 spec).
