Seriously, this. There is NO indication that the Remote Desktop feature is an Pro/Enterprise Only feature. You're going to lose customers because they will simply try a limited deployment on 2 systems using the free version (maybe on their home PC and their Kid's PC, like I did) and give up on making Remote Work (like I did) and move on to the next product that has better documentation.
Then, later down the line, they will come back and work on why the Remote doesn't work, find this and with an exasperated sigh they will say "Oh, well. We're already using PRODUCT_B."
