Re: pstricks in org-mode?

preview-latex in AucTeX works really well I think. It would be nice to use
it in org-mode.
I'm not a lisp programmer. I would be happy to contribute to org-mode but I
need support.
Could someone point me in the right direction to start developing such a
patch?

Or, if someone more skilled than me would like to pick it up and just do it,
that would
be fine with me!
