G'day Remy
Yeah your answers make sense - I wasn't sure if it would be possible or not
but I thought I would ask just incase you had some miracle answers.
I'll stick with the firewall and the TCP server for the time being. I can
get MAC address's using the IP address of the networked computer. This is
for a private network only (using wifi) so it should be safe from the web.
Just wanted to restrict it a bit though. I'll simply set the server to
disconnect if the MAC isn't whitelisted.
Thanks
Jamie
