Yes, indeed it does!
Since I read the announcement this morning, I have been playing with
MathJax. I found that when an HTML file on the local hard disk uses
MathJax from the web, MathJax reverts to image fonts in Firefox (this is
caused by a security feature of Firefox and mentioned in the MathJax
FAQ). Using a local MathJax installation in a subdirectory fixes this.
Most of my time was spent messing around with XULRunner to load the
exported HTML page, wait until MathJax has done its magic, then
serialize the result back to XHTML.
And replace the file:// URLs pointing to the fonts of my local MathJax
installation with data: URIs, thus embedding the fonts within the HTML
file itself, just because I can.
The result is a single HTML file which does not require JavaScript to be
viewed (and incurs no delay while the math is being rendered). However,
as no MathJax code is present, the zoom and view source functions of
MathJax are not available.
I have put an example online.
Normal org-mode export using MathJax from orgmode.org:
http://www.jboecker.de/2010/08/14/mathjax-example.html
Single-file no-javascript version:
http://www.jboecker.de/2010/08/14/mathjax-example-nojs.html
Internet Explorer will not use the correct font, AFAIK because it only
supports the EOT fonts (MathJax uses OTF for other browsers), and in
this case also because I embedded the fonts using data: URIs and IE
limits the size of data: URIs to 32 KB.
In browsers other than Firefox (I tested with Firefox and Opera), the
font size and spacing will differ slightly between the two versions.
If people are interested, I can try to make the program take the name of
a file to operate on as a command line argument, so this could be run as
part of an org-mode export process or something. Of course, the
embedding of fonts in data: URIs would be optional.

And don't forget that on modern high resolution displays, it is common
to zoom in just to be able to decipher math in images, especially if you
want sub- and superscripts to be legible.
