how many VR users can this platform support simultaneously?
is there a limited amout of space available in the ecosystem, so that scarcity is present?
They will probably have problems in the beginning if there are a lot of users. Just like in the early days of email, when someone attached a file in a mail, ''internet would crash''

It will depend how they will create their infrastructure. if it's blockchain based it would be decentralised enough to handle big loads.
