What do you use for generating GUID in OSX? Does OSX have a GUID
generation API/syscall? What is its algorithm, does it show the MAC
address verbatim on the resulting GUID?

Interesting. Care to share your plperl code? I would expect Perl to be
not so far behind C for this (at least if your using hex() &
pack()/unpack() and the "b" template; since the hard work will be done
in C routine anyway).
