I (=author of texvc) certainly didn't.
Windows on servers is not really relevant.

I originally planned to use popen2-based interface, but for some reason
it's off by default in PHP.

In such case texvc.ml's lines:

Texutil.set_encoding (try Sys.argv.(4) with _ -> "UTF-8");
try render Sys.argv.(1) Sys.argv.(2) (Parser.tex_expr lexer_token_safe (Lexing.from_string Sys.argv.(3)))

need to be replaced by

Texutil.set_encoding (try Sys.argv.(3) with _ -> "UTF-8");
try render Sys.argv.(1) Sys.argv.(2) (Parser.tex_expr lexer_token_safe (Lexing.from_channel stdin))

If your php is compiled with popen2 (does it work on windows at all ?)
you could just put formula onto it's stdin, close it, and then read answer from
its stdout.

Your best bet is probably to use Cygwin and their shell. They have an
rxvt-nox that works great. I have the base X11 font that I ported to
Windows on my website: http://www.twoevils.org with instructions on how
to use it with Cygwin (www.cygwin.com/setup.exe)

I agree. When I started (to install a wiki on Windows) I thought it would
not work. Astonishingly, it does, at 95%. I pursue, and share my
experience, so that you and the others know some of the answers if somebody
else asks about such an irrelevant scenario! If ever I want to install
something widely open, I'll do differently (what I do is on a small closed
network).

Perhaps I should add some language into the README to that effect:
this code was developed and tested on and for Linux. No attempt has
been made to make it portable to other OSs, though it just might
hapen to work on some. If you attempt this, you do so at your own
risk and without support.

I think it should work on other Unices too.
It's just Windows that's too different.

I doubt it's a DOS problem -- some DOS commands require passing of + on the
command line (attrib and copy for example). Try typing "echo +" if you don't
believe me.

It might be a PHP bug. I couldn't find any mention of it in
http://www.php.net/manual/en/features.commandline.php . You might have to
just think of a workaround. Maybe you can try using W32api to call
GetCommandLineA, if you're brave.
