So to clarify, your solution still requires a desktop/laptop machine to run enscape and stream the experience to the wireless Quest? Its great that this is possible...
...However... the biggest barrier to client engagement is the GPU requirement. Its not reasonable to have a dedicated VR capable machine for each person in a meeting and it diminishes the usefulness when people a have to take turns to participate.
If the Quest could run an optimized/"game-ifyed" EXE file, we could buy enough quests for a small army of meeting participants and simply push the exe to each.
Iris VR Prospect has had multi-user and untethered Quest support for a long time. The visual quality is just severely lacking but the functionality is impressive.

That hardware barrier will not go away anytime soon.
While it is not even yet possible to fit the Quest with the hardware in it to accomplish real-time raytracing, if it were, the cost of the headset would be well over $2000 and that would become the barrier to outfitting a room full of people with what is needed to reach the pinnacle of what we are after here, Our goals are the same after all.
Yes, we have experimented with IrisVR, Insite, TheWild etc. They all can work natively on the Quest, and they all have the same visual fidelity issue due to the resources on the Quest being inadequate. Strip an Enscape file down to what would run on the Quest natively and we are going to be in a similar situation, but Enscape does not have the collaboration features that the other products have.
VR Chat is probably the best bet for everything you are after today, but the application comes with an unprofessional slant, and a lot of work optimizing scenes through Unity.
Consider this option, there is a cloud compute offering available today that gives access to a remote PC that is outfitted with a GTX 1080. In theory, similar steps as outlined above can work with this cloud PC as well, and the service to access the cloud PC is $12-$15 per month, with new higher-spec offerings coming soon. Enscape supporting multi-user collaboration is now the only hurdle in achieving what is desired if you have the capability to do the above steps as we would be able to provide a client a login for the cloud PC to view the VR from their home/office utilizing only an Oculus Quest and a good internet connection.
This wireless VR setup today is just a stepping stone to get to the ultimate goal. We have overcome some of the "wait your turn" issue by mirroring the VR participant's view to a large screen or projector in the same environment. It is not ideal, but it is what we have today, and our clients are finding it useful in sparking discussions that would otherwise not occur. The pandemic is another factor making it impossible to continue using Enscape to collaborate in that sort of environment, but we have the scenes set up for Enscape already so we have been rendering to 360 and the clients are using these during zoom meetings effectively.
