It would be awesome for you to offer multi rider support for the same log in via a family or group plan of some sort. I have a Computrainer. Have it hooked up to Zwift and it works fine but my SO who typically rides with me is unable to ride unless we bring up a SECOND computer with a different account so he can ride too. I haven’t purchased the second account because I’m not sure Zwift is for me given the many limitations. A big one is PRIVACY. I can’t hide my personally identifying details from others.
Computrainer software was buggy and didn’t offer much in the way of interactive technology. That said, they DID offer the capability to do multi-rider and keep details hidden. PLEASE consider this. I know there are MANY people who would pay an additional fee for this capability.
