Copies of your app running on the local net

[Mark Schonewille]

Hello Paul,

reply 1) Yes, you can broadcast a UDP request and make all copies on  
the network send (part of) their serial number to compare them with  
the serial number of the newly opened copy of your application.

reply 2) Yes, you can use USER$ on some platforms, but not all. You  
can also use MAC address, label of the hard disk, IP address and  
other characteristics. However, I will never buy software that  
requires me to provide information like this, because I know it will  
be a hassle to install the software on a new machine. Besides, there  
is a hack for each protection measure which makes it difficult to  
decide how much to invest in protection.

Best,

Mark
