I don't think that would be helpful for me. I need the server to verify
a particular client. That client is behind a NAT, and the client
address is set by DHCP, also the client IP address is very generic,
i.e. 192.168.1.x.
I need the server to check the client for something unique. Maybe a
machine address, or a special hidden file.
I am sure this can be done. Although maybe not from PHP. There are
companies that have web-time-cards. I think the commercial
web-time-card apps, may be initiated from a app on the client side. The
desktop app then connects to the server.
