Re: Accessibility, perfect or better Re: hit testing and retained graphics

I think your reply lacks substance.

Corporations are -have already- more likely to support the canvas spec because it is small, maps well to their 2d apis and is supported well by other vendors, it is in demand. It costs relatively little to support canvas. Approx $15k per implementation.

Your other statements are rebuttals without citation/arguable points.
