User name is one of the thing he can use. It can be used in conjonction with
other values like the processor type, os version, MAC adress (if present),
etc.... . There is no perfect way to uniquely identify a device when there
is no serial number exept the mac adress maybe. It was greatly discussed in
other treads.

Using the tick will provide a different number if the user reinstall its
software after a hardreset witch will force the user to contact you to get a
new access key (unless this is what you want).

The user name doesn't provide very good protection against duplication: two
different users of the application could easily have a user name of
"Tom".  What our company has done doesn't provide absolute protection
either, but it's better than the user name: the current system time in
ticks.  We actually just convert the values returned by TimGetSeconds and
TimGetTicks into strings and concatenate them.  If you look at the
definitions of these two functions, you'll see that accidental duplication
of this value by different users is very unlikely.  Of course, we only use
this value as a fallback if there's no ROM serial number to use.  Either
way, we capture the chosen identifier just once and store it in the
Preferences database.
