Yes, I mentioned this in my original post:
http://www.mail-archive.com/numpy-discussion@scipy.org/msg29324.html

But good simulation practice is perhaps to seed
a simulation specific random number generator
(not just rely on a global), and I don't want
to pass around two different instances.
So I want to get this functionality from numpy.random.

Which reminds me of another question.
numpy.random.RandomState accepts an int array as a seed:
what is the *intended* use?

Thanks,
Alan
