I don't know your need for this, except for some validation purpose.
If so, each Squeak image on each machine could generate UUIC , you could
validate this .

if you're willing to write a plugin here's a native snippet of C/ObjC you can use to get the serial number.

   io_service_t platformExpert = IOServiceGetMatchingService(
       kIOMasterPortDefault,
       IOServiceMatching("IOPlatformExpertDevice"));

   if (platformExpert) {
       CFTypeRef serialNumberAsCFString =
           IORegistryEntryCreateCFProperty(platformExpert,
                                           CFSTR(kIOPlatformSerialNumberKey),
                                           kCFAllocatorDefault, 0);
       IOObjectRelease(platformExpert);
   }

Hi Edgar,

It's for a licensing server. I think I've found a way to do it using
the ethernet physical ID trough:

Applescript doIt: 'do shell script "ifconfig en0"'.

And then filtering the physical address.

This won't work. Usually the MAC address shown is only a copy
of the number stored on the device. You can alter this address
easily.

I assume simply replacing the ethernet card - or even just adding one and reassigning which is en0 - would mess it up pretty badly.

Many CPus have an actual unique ID that is findable somewhere. Even there you're in trouble if the cpu has to be replaced due to failure of upgrade.

The next generation of computers will have a "Warranty Expired" interrupt.

This won't work. Usually the MAC address shown is only a copy
of the number stored on the device. You can alter this address
easily. Under linux this would be

ifconfig eth0 hw ether 00:11:22:33:44:55

If you're after licenses you may do some poor microsoft style
checking. I quick search on google showed the pendant for lspci
on linux is called pciconf on bsd-like systems. There you get
the real device ids of all devices attached.

Try (in 10.5):

 ioreg -l -w 0 | grep IOPlatformSerialNumber

but what about other OS versions?

Yes, that is hardly avoidable. I think that's the reason so many
companies still use some sort of dongle.
