Bruno's advise is still valid. If you google around a bit, you'll across
explanations like the one in
on how MS-GUIDs are created. If fitting to your GUID-loving-app is the
key here, you can easily write a function in C or other language that
when called it returns a GUID in the exact format you need.
substr(random(n,m,sha1(rand(ms_since_epoch())))-[unique ID generated
from your MAC address]
or something like that - you get the picture.
