Hello,
I need JFusion plugin for user integration from CS-Cart in Joomla.
JFusion ([url]http://www.jfusion.org/[/url]) is a free GPL Extension for the award winning Content Management System (CMS) Joomla. JFusion provides universal user integration, by extending the Joomla 1.5 user authentication framework without any core hacks.
Thank you for your response.

Bump! JFusion is brilliant!
A “bridge” plugin or add-on between jFusion and CS-Cart will further increase the features and make CS-Cart more attractive! 
Or, a bridge from CS-Cart to JomSocial for Joomla!
