That's technically true, but in this case, we already have at least 3 
native implementations in Firefox, Opera and Safari, and a working 
scripted implementation for IE.  Plus, as my examples showed, it's 
already being widely used.  So any alternative solution that completely 
abandons the existing implementation and usage would be extremely 
unlikely to succeed.

If there are problems with canvas that need to be addressed, then that 
is certainly open for discussion.
