What I would like to see is a node that generates a simple random
number, math node or so. I could then take this number and feed it
into a combine RGB node to make a random color Or into a Ramp Node or
whatever. Of course it could have many other uses. The problem now
with things like Object_Info Node Random is that if you feed it into
the RG and B inputs you of course get different grays. You can't get
different colors because all the "Random" numbers are the same. This
is one reason I suggested seeds and also a time input to the seed to
have the choice of random seed input or not. A script node is not good
enough do to speed and CPU only rendering, more the CPU though but
that is a speed issue too.
