The Javascript application included on the community.edition is almost
exactly the same it is running live on the Clipperz site; the only
difference being the new Proxy.PHP to talk with the PHP backend that is not
yet included on the live version.
The backend used on the live version on the Clipperz hosts is completely
different: written in Java, using PostgreSQL, and with many extra feature
to make it run smoothly.
The connection stats are not collected by the current PHP backend.
I have no plan to add this feature soon, but if anybody is willing to add
it, I am very willing to help.
