I installed it on my site. With Joomla. I'm not actually using Joomla, I'm just using it to connect some of the "pieces" of software on my site.
JFusion is a very high tech extension. I think it's more significant than Joomla, which is just another CMS and I had such a rotten time with the installation that I would have trashed it, if not for the fact that I wanted JFusion. JFusion is very unique, I've never heard of anything like it out there for us to work with. There's a zillion CMS systems but only one JFusion.
JFusion imports, merges, syncs users in multiple databases and it creates a Universal User, so when a user logs in to one module, the user is automatically logged into all modules in the JFusion framework.
Like I said, I don't have to use Joomla. JFusion works with plugins or componenets, inside or outside of Joomla, to coordinate everything with a "Master" database. And the master doesn't even have to be Joomla, either. I chose my forum as the master.
JFusion includes a folder with MODEL files, from which developers can very easily configure a JFusion plugin. Here's the one page instructions on how to do it:

The files are in the JFusion download.
No, I'm not a member of the JFusion team. I just REALLY want to INTEGRATE my site, and I really don't want to give up ZenPhoto just because it doesn't integrate with anything. That I know of.
With this ONE plug-in, that's already basically set up for you, then ZenPhoto could integrate with a whole lot of things. So I'm really hoping that JFusion will inspire the developers here at ZenPhoto.
