I actually helped somebody else get this working with the older version and had no real problems. The biggest issue is using it over the internet where local router firewalls cause a problem.
I put the server on a Raspberry Pi and had two instances of VaM on my desktop connect to the Pi and it all worked perfectly. The user in VR could interact with the person controlling the Desktop VaM model.
I can see a lot of scope for developing this. I can't wait to see what's next and hope that this can be integrated into VaM2.0 when it finally lands.
