Has someone tried it? On a 1st try I've noticed extensions stop working. For example if I set define( 'CIVICRM_TEMPLATE_COMPILEDIR', '/tmp/civicrm/templates_c/'); would it work? (instead of ABSPATH.'wp-content/uploads/civicrm/templates_c/) I need it for a civicrm install under WPEng hosting where they do not allow php script to write into another php script within wordpress. Hence re-generating the templates_c files is a problem.
