This requires a cautionary note.
The method above is simple in the univariate case (where people would
usually start with a uniform distribution), however, generalizing it
to the multivariate case, is not as simple as Thierry as suggested.

That doesn't necessarily mean that his solution is wrong.
(Because there's more than one way of defining a bivariate Poisson
distribution).
