Plugin which allows to extend the syntax by configuring external WEB services. For example, code like
<latex>\int \frac{x^2sin(x)}{Ln(x)}" title="\int \frac{x^2sin(x)}{Ln(x)}</latex>
could be replaced by image loaded (and cached) from
http://latex.codecogs.com/gif.latex?\int \frac{x^2sin(x)}{Ln(x)}" title="\int \frac{x^2sin(x)}{Ln(x)}
. Configuration shall allow to specify the tag, for example latex and some simple template with one or two arguments. In the previous example template could look like
http://latex.codecogs.com/gif.latex?$$s
. Where $$s will be replaced by the whole string enclosed by the latex tags.
