Networking ~ Server Max Client Support and Royalty Question

[Synthetic]

I just found out about GLBasic about a couple hours ago. The speed is highly impressive. I was wondering if there is a limit to how many clients you can have connected to a server. Also, I looked at the networking tutorial supplied with the sdk demo and it mentions that when a player sends a message in a session, all other players receive it minus sender. I am needing the abillity to have multiple players (50 to 250) connected to one server but if a player sends a message it only goes to the server for handling and not all the other players. Can GLBasic do this?
Now on to the royalty part. If I purchase GLBasic and make a game with it for commercial use, will it be License and Royalty free?
Thank you for your time.
