More account options

I would like the ability to have many users under one umbrella account

It is already possible. Create more keys in the Devices menu in your client area and give your other users config files with their own key. They can use any server on any protocol/port combination, just like you, but it's limited to five concurrent connections, as you might know.
This won't work that good with Eddie, but the idea is, as the name says, that you create keys for your own devices. For multiple users create multiple accounts so that every one can curate his/her own list of devices.

A consolidation of accounts to a "superaccount" would present a perfect ground for abuse. People will sign up with a group of other people, one of them having control over the superaccount. When the latter subscribes to the service at full price, each member needs only pay a fraction of it. A win-lose situation for AirVPN, because otherwise all members would've subscribed separately at full price.
