I have about a dozen Dolphin licenses.
I was going to get more licenses but ran into roadblocks as what I wanted in the community did not seem feasible with Dolphin.

With Joomla, I found modules that could do what I needed.
I spoke to the JFusion guys and they told me to contact Boonex.

There was one mod developer who actually did do it. I tested the integration myself on his site. But I found a few minor bugs.

If you could integrate Joomla and Dolphin the possibilities are wild.
