All OS have a way to enumerate all mac addresses (sometimes there is 6,
and eth0 can vary over time including if you have two ports by just
plugging the cable in other port) for you to strcmp
The other scheme I have seen is to use disk ID, this is more common for
temp licenses then permanent one though.

Mike,
If you're on a commercial workstation, and are not using a plug-in
network adapter card, then the MAC address will be unique, although
some (most?) workstations have not one, but **two** network
interfaces, so there will actually be two distinct MAC addresses. If,
however, you're using a plug-in card, you run the risk of crashing
your software if the network hardware is upgraded.
It is also possible, on Intel CPUs at least (not sure about AMD) to
obtain the CPU serial number. Microsoft has the '__cpuid' macro that
generates in-line, the MASM to obtain this:

That ties your software to a specific CPU (assuming CPU identification
is enabled in the BIOS), and is much more reliable.

Hi Steve,
I can see how this would work when tying the plugin to a specific
domain but how would you approach locking the plugin to a single
machine? Use the MAC address?

Mike,
How you do it depends on the OS platform you're using. Generally
speaking, what I do is to get the domain name from the network stack
(or just using the Win32 API under Windows), and compare it to a const
string. Thus, if you're working within, say, Disney Animation, and
the compositing domain is comp.disney.com, for example, just error()
if the domain does not match this string.
Hope that helps.

If I recall correctly, this License API is no longer available
according to a thread I checked a while ago.

Is it possible to provide any more info on how a 3rd party can
implement licensing within a plugin? I want to have a look at the
very least locking the use of a plugin to a specific site, not really
interested in floating licences or anything particularly complicated.

Can't really make much sense of this. How does the system ID work.
'This is a 32-bit value that is unique for each customer site'. I
check '$this_system_id' here and get 0 as the result. I'm not even
sure how this is meant to work!
Cheers,
Steve
