Why is this client plugin named jQuery? It has not much to do with jQuery. A name such as "Etherpad JS wrapper" or "Etherpad JS embedder" would be more suitable. This name is really misleading...

AFAIK it really only creates a wrapper

Additionally when one admin says to another one "Hey, I use the Etherpad jQuery plugin on my server XY." it is not clear at all that this is a client-side plugin. I'd rather think it is a plugin I can install on the server.
This is not only theoretical, I misunderstood it this way.

So you might rethink this name.
