That was my thought when I saw it done too... The PDF I linked to at the bottom of the article shows a full implementation in C which is pretty awesome. If I remember correctly it's only a couple of hundred lines long.
At the moment I am in the process of writing a VM which provides basic functions tailor-made for implementing a language this way. Should be interesting to see how it turns out...

The send macro is a particularly clever bit of the C implementation. It uses GCC ({ }) compound statement-as-expression macros and static variables to insert an inline method cache at every place that you send a message to cache the result of lookup.
Feedback is warmly welcomed as always. If any of the HN crowd sees issues with this approach I would love to hear about them before I commit to building this into my final language...
I'd love to see an example of such a protoype based object oriented language in x86 Assembly language.
Haha, well it wouldn't be easy, but it is certainly possible.

Added: This isn't a particularly simple example, but I just found a good looking PDF on OOP in C that seems worth sharing: http://www.planetpdf.com/codecuts/pdfs/ooc.pdf
