Daniel does say that it is coming, which it is/has. He never said how. Beautiful use of “consumer curiosity” marketing by the staff on that one. I read your “business proposal” part as more of a personal sticker shock, not a suggestion. $20/mo is not unreasonable, in my opinion, for what is offered.
Now then, for what you want to do (Mark, Daniel, can you shed a little light on what I am about to “say” as far as yes/no?), I see no reason that your company can’t get a premium account and give those who want it, the userid and password, or, be able to put multiple logins under one account. Then again, if you are using it for a business, there is a reason it is called a “commercial” account.
Expanding the current settings for the free accounts will devalue the current commercial options, which would mean their prices would go up, thus, leading to fewer possible “upgrades”. I, like Dave (dami), have no reason to track more than 5 aircraft at one time.
It is just a pet peeve of mine on this site that users want the staff to expand what is available for free, especially when they realize they may have to pay for a little more “access”.
