I got this submission from someone and wanted to know what the VR community
thinks of it before I go on and add it or not to the "VR term" database.

Is "transport delay" a term that is widely used in the VR field?

I'm not sure if I want to add yet an other term linked to "lag" and "latency".

You can post or e-mail me your opinions.

Thanks for your help
