[gmpi] Re: GMPI SDK snapshot online

Because the standard (yes, there is a standard, but I forget just which one) defines it this way. One part is the physical network address, another part is the time, and another part is a random number.

This is probably a stupid question, but why define the GUID this way?

uint16_t data2;
uint16_t data3;
unsigned char data4[8];
};

Why not just a single `unsigned char data[16]'? 

I have no idea - all the code I could find on the web did it this way,
which does not even correspond to the standard printed notation.  For fear
of horking byte-ordering, I stuck with what I saw in use :)
