ah, 6 users means the service costs as little as $5.83 if you do it right.

Doubtful, outside of single-household sharing; I'd be very surprised if they got to avoid the contractual terms that limit your ability to share a PS Vue account in the same way - you have to activate a "home device" to anchor the account and regularly using six different devices in different locations would probably trigger some sort of fraud check.

You can have 6 user "accounts", but only three simultaneous streams.
