Oh, you can use InlineReplacement and DoubleBrackets to call functions--
no problem.  Assuming that OpenMathTag returns a MathML string (as opposed
to outputing the MathML markup directly), you can do:

    $InlineReplacements["/\\\\\\[(.*?)\\\\\\]/e"] =

If OpenMathTag doesn't return a string, then you can call your own 
function that captures the output of OpenMathTag into a buffer and
returns it as a string.

This is indeed a tricky part.  One of the things I've been thinking of
adding is a mechanism similar to $DoubleBrackets/$InlineReplacements
that allows some markup to be processed before PmWiki does any conversion
or line splitting.  This would certainly work for OpenMathTag, and also
give sites the ability to allow HTML/XML tags.  It would probably
work just like what I wrote above, except use an array other than
