I need to integrate something like this in an open source platform. Is there anything even close as an open source project? Or do we need to develop the same thing as FOSS ourselves?
It wasn't me. Someone down voted me too. Sometimes the HN crowd is a bit negative against open source as they are focused on making money and there is some who think there is a conflict in that.
and distributing a web-app would equal to just open source it.. I know, it's a dilemna
