[texhax] interactive tex

[Michael Doob]

I recently built a web page for interactive tex: html input of
type=text is used to enter the TeX source and a page is generated with
the corresponding TeX output. 

In my case I am working in a LAMP environment (P=php), so there
were a number of options available: I used dvipng to generate
the TeX output to be displayed. I wasn't totally happy with
my results, so I'm asking the following question: what's your
favourite way to implement this type of interactive TeX? I guess 
there are actually two slightly different answers: one for trusted 
users and one where the input has to be scrubbed (with something 
like the php escapeshellcommand function).

Cheers,
Michael
