wine users - Jan 2011 - get unique code identifier for computer (license key calc)

I've developed a windows application, that on windows get the hard disk
number for generating a code number, with this number i've a keygen that
generate a validation key for activate the program.

This application runned on wine return always the same code because the hard
disk number is the same for wine.

How can i generate a valide unique code for the computer where application run
under wine ?

Is there a way to calculate a per-machine unique number ?

Thanks.

HDD serial number is a very bad choice. Whenever user gets new HDD your
protection will break. Wine doesn't even return the actual HDD serial number
because Wine has no direct access to disk to read it.

Most unique numbers present on a computer can be faked with Wine. It's open
source and no one can prevent a person from modifying Wine source code. All
protection schemas that tie to some sort of serial numbers of a PC or a
component can easily be broken.

The only viable protection is hardware key (e.g a usb dongle). Or online
protection (verification with server that user has valid license and that
license is used on one computer at a time).

Of course any protection needs to be well integrated into software itself so it
can't be easily bypassed.
