Hi,
for SugarCRM I have come across a Joomla user, a VirtueMart plugin and a Community Builder plugin, that seem to work well, but no one for HikaShop.
Personally I also want to use SugarCRM for our direct marketing and customer support inside and outside joomla - and I am currently looking for joomla people who want to support a bridge from SugarCRM to acyMailing (Enterprise).
As SugarCRM will discontinue its Community Edition in 2nd QT 2015, I will also choose a derivate 100% based on the core SugarCRM CE 6.x - in my case EnjayCRM.
Anyone who wants to join efforts for a SugarCRM to acyMailing bridge?
Clemens
