(Speaking only about my personal perception and *relative* non- 
worriedness.)

I didn't mean that I don't consider patents dangerous. I do. (I think  
the EOLAS case is a great example about what's wrong with the patent  
system on one hand and what's wrong with trial by jury on the other  
hand.)

My (perhaps misguided) non-lawyer hunch just is that the <canvas>  
patent scare has been overblown after the forwarded message from the  
Apple lawyer (to which the best response is to publish <canvas>  
through a W3C WG in which Apple is participating). As far as the  
graphics algorithms go, Microsoft is already shipping WPF, so  
Microsoft is already on the hook for the kind of back end  
functionality <canvas> requires.

As for potential patents from outside the WG, I really don't see any  
real reason to pick <canvas> as the subject of unsubstantiated patent  
scare instead of any random feature.
