	If I'm not mistaken, a Poisson source is defined by two criteria:
(1) exponentially distributed interarrival times and (2) exponentially
distributed packet sizes (i.e., service times). Using these two properties
you should be able to write a Poisson traffic generator. I don't think
there's one implemented in ns-2 at this point, so it could be an
interesting contribution since this question comes back pretty often.
