Question: not knowing anything about browser plugins, will it be possible to build a "Click to Canvas" plugin, similar to the Click to Flash plugins avialable? It seems like anything that can access the DOM can insert stuff into (override) or outright block elements, right?

I'm sure we'll see such a thing. The problem is that it'll just shift to somewhere else in the browser, and killing off all the codepaths that might be doing something to the non-working canvas might be subtly hard.

It'll stay a game of cat-and-mouse for a long time I'm afraid.

Good points. Thanks. I guess it's inevitable given the free (as in, subscription free) nature of web content. Heck, even paying a subscription to the NYT doesn't opt you out of seeing their ads, unless you take matters into your own hands with something like AdBlock.
