It is working nearly the same way with joomlacomment. What you perhaps don't understand from the above example you gave is that jcomment has an internal plugin for phocadownload. We should first write one and then you can integrate joomlacomment with phocadownload.
It takes around 1h to 2h to write a plugin for a component. Right now I don't have this time, because my efforts are concentrated on joomlacomment 4.1 beta1.
