Jump Host : Understanding

Hi .. Just a quick clarification ..

To run a website only through a 'Jump Host' I have to have RDM installed on the 'Jump Host', and when I set the session up it essentially opens that copy of RDM inside my RDM (showing double).

Is there no easier way to do it ? With some sort of 'agent' on the 'Jump Host' and the window appearing in my RDM looking like I launched it on my copy of RDM.

The information makes a correct link with the fact that sometimes only some items can be launched on a 'Jump Host', but usually those 'Jump Host' machines won't allow for a full copy of RDM due to security rules. And anyways .. if I wanted a window of RDM in RDM .. why not just setup the RDM with a DataSource in the 'Jump Host'.

Hopefully I watched an old video and someone can tell me that I am wrong.
