Answer 1

There is no uniform answers to this. It depends on if you have access to the connection list. If you have access to the AP then it simplify things easier. If not, you can attempt to send a message all 254 IP addresses: 192.168.1.[1-254].

For users who are connected using WinXP or older. You can send a message using net send

For users who are connected using WinVista or newer. You can send a message using msg

For users who are connected using Linux. You can try: smbclient -M hostname message goes here

For users who are connected using MAC. I have not seen this yet.
