Programming a license mechanish under Linux OS

Hello!

My thesis advisor and his development team have designed a nice software for ray tracing in computational geophysics and they are interested in commercialize it for government companies, so he (my advisor) asked me about the license mechanism of software products.

He would like to know (and me too, since knowledge is always useful) what is it done (under Linux OS) in order to limit software functionality depending on the purchased time according to any license terms anyone might be interested in.

The program is being developed under C++ using `(QT + OpenGL) under Linux OS. Mainly under Open SuSE.

Greetings and happy holidays! 8-)

Re: Programming a license mechanish under Linux OS

Not much can really be done but you could make it require a serial code which the installer encrypts into a file in the /etc directory that you read to check at start-up.
Or you can make it go online and validate on your server using sockets for the mac address if you make it send out the mac address during installation?

P.S be creative... more creative you are the harder it will be to crack (trust me I am an ex cracker)
