whilst appreciating that the WebAPI WG might nominally be a more  
appropriate space, it remains the case that there are a number of  
replies outstanding, and activity appears somewhat belated.

in particular as usual much of the query was if not SVG specific, at  
least graphics related.
especially the failure to engage in authoring tool development and  
the effect on standards development...

nonetheless forwarded at your request.

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  
DOM-related spec (with a dependency on the Progress Events 1.0 spec).
