support (e.g. as plugin) for processing pandoc JSON format (like filters but via network/unix socket)

Seems gitit does not support applying Pandoc filters.

I am setting up a workflow similar to http://gitit.net/collaborative%20authoring. Some of my needs for the resulting PDF design can be solved by use of a custom XeLaTeX template, but some need tweaking the text content. I currently use perl regex but now try recode that as Pandoc filters. I then look at gitit for allowing authors to edit content and instantly fetch a resulting draft PDF - but would then need my Pandoc filters applied as part of the export.

If curious, my concrete use is for editing reports at the European Parliament (didn't succeed for http://islandsofresilience.eu/ and now try again for http://euwiki.org/EUT/2nd-edition). My draft messy code is as at http://source.epfsug.biks.dk/?p=eut.git.
