Thats totally cool...

I always liked the idea of a .lic file, your app attempts to
exclusivlely open a 1 byte block until it suceeds and keeps the block
locked whilst running, This way a 10 byte file would allow for 10
users, if the system crashes then the system is self-fixing, no messy
unlock procedures, also the name of the lic file can be a hash with
the size (stop some smartass hacking it with notepad)
if no lic file is found demo mode is used, if it fails to open a block
in the lic file, 'out of users' error

My preference is for licencing information to be stored only in one
central
shared file on a server, nothing in pc registrys, so that when a pc is
upgraded or replaced there is no reinstallation needed.
I think I can do a simple and pretty foolproof scheme based on this
What do others use?
(I would only use another scheme if it was not using registry stuff as I
want centralised administration)
