I did this with the comments box on my blog. I don't think it's technically effective, because doing proof of work in JavaScript is orders of magnitude slower than doing it natively (especially with GPU acceleration). It works well enough for me, because I'm not a big enough target, but it wouldn't be a major obstacle for someone who really wanted to cause havoc.

It would be interesting to see how fast you could make the JavaScript code. I'm sure my version is just terribly unoptimized. The requirement to support the least common denominator will present a major problem, though.

I would look at asm.js, do some tests with major browsers and beef it up. It would make it painful under user agents that don't JIT (or compile AOT) by leveraging asm.js conventions (many do though).

If the wasm effort works out (it's looking like it will), it would hopefully alleviate the issue you present entirely and make this solution viable in a very sane way.
