Both of these are excellent ideas, and I would really like to implement
them, but when I think about the hoops I would have to jump through
to get our IT guys to implement this stuff on our servers, I have
to abandon the idea right there and then.

Great products though.  Thank you for bringing them to my attention.

Thanks for your time here.  These look really well rendered.
Unfortunately I'm again stuck between a rock and a hard place again,
having virtually no control over either my server or my client side.

Now this is a neat idea.  This sounds very close to what is done in
the picmath environment.  Or am I misreading something?  Are the png
files created statically or dynamically?  Wait a minute, I think I see
what the difference is.  You are completely segregating the math
to a separate dvi file rather than picking through the document
one thing at a time.  I'll definitely be interested in this when you
have it fit for public consumption!

I see.  A more stunted sort of LaTeX/Tex then.  But they are definitely
using the cm fonts there!

I'm sure this will be the way to go eventually, but for really
complicated stuff, it still falls short in myopinion.  Like I said,
I tried running my document through mzlatex, but the results really
weren't all that readable.  Perhaps I was doing something wrong...

Thanks again for all of your time.
This is interesting stuff!  It's neat to get a glimpse of where the
leading edge of the browser world lives!
