I've not looked at the source, but if LL implemented the standard for
UUIDs (aka GUIDs) then they shouldn't be completely random at all.
UUIDs aren't made up of all random parts - they have components that
have to be generated in specific ways, only some of which are intended
to be random.  The original (V1) UUIDs actually contain the network
card Mac address of the computer that generated it (!)

Look at SL keys - they are all of the form
xxxxxxxx-xxxx-4xxx-xxxx-xxxxxxxxxxxx for a start - and there are other
internal consistencies I believe.

It may be that LL didn't follow the standard at all and just made up
their own system of course.
